Roblox may look simple to run, but a low-spec machine can still stutter in a packed server on Brookhaven or a complicated obby. The difference between a choppy experience and a buttery 60fps comes down to a surprising amount of CPU and GPU headroom, especially as Roblox Studio, the creation engine for the game, continues to demand more. The best desktop computer for Roblox is one that stays smooth even when a developer friend spawns a hundred neon cars in the same space.
We rounded up ten desktops that span the range, from dirt-cheap renewed business towers to purpose-built gaming PCs with discrete graphics. The STGAubron gaming desktop is our pick for most people: it balances an older but powerful i7, a Radeon RX 580, and enough RAM to keep Discord, Chrome, and Roblox open without a hiccup.

1. STGAubron Gaming PC: Best Overall
Pros
- Radeon RX 580 8GB handles Roblox at max settings with 60+ fps
- Wi-Fi 6 and Bluetooth 5.0 included
- RGB fan kit and gaming peripherals in the box
- 512GB SSD for fast load times
Cons
- CPU is a few generations old
- Case has no glass side panel
Best for: someone who wants a dedicated gaming desktop that plays Roblox, Fortnite, and modern titles at 1080p without spending over $500.
The STGAubron does the one thing that matters most for a Roblox machine: it keeps the framerate locked to 60fps even in chaotic servers. The Radeon RX 580 with 8GB of video memory is overkill for Roblox today, but that headroom means you can run Roblox Studio, a browser with five tabs, Discord, and Spotify simultaneously without a single hitch. Many of the renewed office desktops in this list use integrated graphics; this one has a real GPU, which is the difference between Roblox feeling like a game and feeling like a slideshow.
The Intel Core i7 inside tops out at 3.9GHz. That is not the latest architecture, but for Roblox, single-core speed matters more than core count, and 3.9GHz is perfectly adequate. You also get 16GB of DDR4 RAM and a 512GB SSD. The SSD is crucial: Roblox's loading screens vanish. The 512GB fills up fast with a handful of big modern games, but if you are mostly on Roblox, it is plenty.
The biggest missing piece is an upgrade path. The STGAubron uses older components, so swapping in a newer CPU later would require a motherboard change. That said, this machine can handle Roblox for years. It also ships with an RGB keyboard and mouse, which saves you a trip to the store. The only real annoyance is the noise: the four RGB fans spin audibly under load. You can tune them down in the BIOS, but out of the box it breathes harder than a modern prebuilt.
For anyone who wants the best desktop computer for Roblox without digging through used market listings, the STGAubron is the turnkey winner.
2. WIWB Gaming PC: Fastest New CPU
Pros
- Ryzen 5 4500 is a modern six-core chip
- RX 6500 XT supports AV1 decode and newer features
- Wi-Fi 6 built in
- Clean white aesthetic
Cons
- RX 6500 XT has only 4GB VRAM, limited for future AAA games
- No included keyboard or mouse
Best for: a gamer who wants a current-gen CPU and doesn't mind buying peripherals separately.
The WIWB gaming desktop uses the modern Ryzen 5 4500, a six-core processor that boosts to 4.1GHz. For Roblox, which relies heavily on a few cores, this CPU delivers the snappiest experience of any machine in this roundup. The RX 6500 XT is a newer architecture than the RX 580 found in the STGAubron, but it has only 4GB of VRAM. In Roblox that does not matter at all; the game rarely uses more than 2GB. But if you ever branch into Call of Duty or Cyberpunk 2077, the 6500 XT will struggle at higher textures.
The 512GB NVMe SSD is fast. Boot times are under ten seconds, and Roblox levels load nearly instantly. WIWB also includes Wi-Fi 6, which matters if your router is in another room. The case is a clean white with a mesh front, and it stays quieter than the STGAubron. No peripherals are included, so factor in a $30 keyboard and mouse.
The one thing that nags: the 6500 XT connects via four PCIe 4.0 lanes, but this motherboard supports only PCIe 3.0, which can bottleneck performance in some games by about 10-15%. In Roblox, that is invisible. Still, if you plan on playing harder titles, the STGAubron's RX 580 remains a more balanced choice.
3. LXZ Gaming PC: Best Value New Build
Pros
- Same core specs as WIWB but often available for less
- Six-core processor for serious multitasking
- Runs Roblox easily at 1080p
- One-year warranty included
Cons
- No display outputs on the motherboard; GPU required
- No included mouse or keyboard
Best for: budget-conscious gamers who want a new PC with a warranty.
The LXZ gaming desktop uses the same Ryzen 5 4500 and RX 6500 XT combination as the WIWB. In fact, the parts list is nearly identical: 16GB of DDR4 RAM, 512GB NVMe SSD, Wi-Fi 6. So why pick one over the other? The LXZ sometimes undercuts the WIWB on price, and it includes a full one-year warranty rather than the industry-standard 90 days. That extra coverage matters when buying a new prebuilt from a smaller brand.
Roblox performance mirrors the WIWB: solid 60fps at the default maxed-out graphics setting, with no drops in populated servers. The only notable difference is the case design, the LXZ uses a white chassis with an RGB light strip rather than the WIWB's full mesh front. Neither is wrong; pick whichever looks better on your desk.
The absence of any bundled peripherals is more keenly felt here than with the STGAubron. A $20 keyboard and mouse set will work fine, but you might want a better mouse for Roblox's precise building controls. If you have a specific type of gaming keyboard in mind, it is worth considering what fits within your total budget.
4. Dell OptiPlex 7050 SFF: Most RAM
Pros
- 32GB of DDR4 RAM, more than any other pick
- 1TB SSD for generous storage
- i7-7700 still a capable processor
- Small footprint fits anywhere
Cons
- Integrated graphics only
- No dedicated GPU for gaming
- Renovated, not new
Best for: a Roblox Studio developer who needs RAM for heavy asset creation and runs the game at modest settings.
This OptiPlex 7050 is the machine you buy for someone building in Roblox Studio, not just playing Roblox. 32GB of RAM is overkill for the game itself, but for running Blender, the Roblox editor, Chrome with dozens of tabs, and a video call all at once, it is exactly right. The Intel Core i7-7700 is a quad-core from 2017, yet its single-core speed is high enough to keep Roblox Studio responsive.
The 1TB SSD is a big upgrade over the typical 256GB found in renewed business desktops. You can store hundreds of Roblox creations, plus a few other games like Minecraft or Fortnite. The small form factor means it slides onto a bookshelf or behind a monitor without dominating your desk.
The catch is graphics. The integrated Intel HD 630 will run Roblox, but only at the "low" or "medium" preset, and expect frame drops in busy servers. If your child asks for a desktop for Roblox, this machine needs a discrete GPU to be enjoyable. The good news: the OptiPlex 7050 SFF has a PCIe slot, and you can add a low-profile graphics card like a GTX 1650 or RX 6400. That project takes 20 minutes and transforms this into a capable 1080p Roblox machine. If you are comfortable with that, this desktop offers the best RAM and storage value in the list.
5. Dell OptiPlex 5060 (Renewed): Best Storage Combo
Pros
- Dual storage: 500GB SSD + 1TB HDD
- Six-core i5-8500 turbo to 4.3GHz
- Includes Wi-Fi and Bluetooth
- Room for upgrades
Cons
- Integrated graphics only
- Renewed unit, may show cosmetic wear
Best for: a family that needs a desktop for school, Roblox, and media storage all in one.
The OptiPlex 5060 hits a sweet spot for a household computer. The Intel Core i5-8500 has six real cores and can turbo up to 4.3GHz, making it faster than many used quad-core CPUs. It handles Roblox well enough at medium settings with its integrated UHD 630 graphics, though a dedicated GPU would unlock high fidelity.
The dual storage arrangement is the star: a 500GB SSD for the operating system and favorite games, plus a 1TB HDD for everything else. That means Roblox boots in seconds from the SSD, while family photos and school projects live on the spacious hard drive. You rarely see this combo in a $250 machine.
The OptiPlex 5060 is a mid-tower with plenty of interior room. You can easily add a graphics card later, and the PSU is standard enough to support a 75W card without replacement. That makes this a smart long-term buy for a kid who is only playing Roblox now but will move to more demanding games in a couple of years.
6. Dell OptiPlex 3060 (Renewed): Best Slim Desktop
Pros
- Tiny footprint, fits in a backpack
- 32GB RAM for heavy multitasking
- 1TB SSD, no moving parts
- RGB lighting kit added on the side panel
Cons
- Integrated graphics capabilty
- No expansion slot for a GPU
- Slightly older CPU generation
Best for: a dorm room or small desk where space is at a premium.
The OptiPlex 3060 in its small form factor is remarkably compact. It measures about 11 inches tall and 4 inches wide, making it one of the smallest desktops that still uses a standard desktop CPU. The i5-8500 provides six cores, and the 32GB RAM is generous. The 1TB SSD means no spinning disks and near-instant wake from sleep.
This machine has a fun quirk: a third-party RGB lighting strip adhered to the side panel, controlled by a button on the front. It is a nice touch for a gaming setup. For Roblox, the integrated UHD 630 graphics run the game at 1080p on low settings smoothly; medium settings may dip in crowded areas. The biggest limitation is that the 3060 SFF uses a proprietary motherboard layout and a small power supply, so you cannot easily add a dedicated graphics card. This is a "good enough for now" machine if you plan to stay on integrated graphics forever.
If you need a second computer for a younger sibling or a compact workstation that happens to play Roblox, this fits neatly. Just know that when your child wants to play The Finals or Fortnite, they will need a different rig.
7. VRA Gaming PC Bundle: Full Ensemble
Pros
- Comes with gaming keyboard, mouse, mouse pad, and speaker
- RX 580 8GB is a proven performer
- Six RGB cooling fans with remote control
- Mid-tower case easy to upgrade
Cons
- Core i7-4790 is quite old
- No SSD; likely uses a hard drive
- Bundle items have budget build quality
Best for: a parent buying a teenager's first gaming setup with one click.
The VRA bundle is the most complete out-of-box experience in this roundup. It includes the desktop, an RGB keyboard and mouse, a large mouse pad, and a desktop speaker. For Roblox, the RX 580 8GB is more than enough: 60fps at maximum settings all day. The Core i7-4790 is a Haswell chip from 2014, but in Roblox it is still capable because the game does not use many cores. Where it shows its age is in CPU-heavy tasks like compiling Roblox Studio projects or running Discord's encoding.
The biggest question mark is storage. The product listing does not specify an SSD, and the description references "high-speed storage" without details. Many budget bundles like this ship with a 1TB hard drive. If that is the case, expect slower boot times and longer Roblox loading compared to SSD-based desktops. You can add an SSD later, but it adds cost.
The six RGB fans are controlled with a remote, which is a neat party trick. The bundle feels like a graduation gift from 2017, but for a younger player whose main game is Roblox, it works. If you want something that will stay relevant for high school, the newer Ryzen systems above offer more future-proofing.
8. Dell OptiPlex Bundle (Renewed): Best Bundled Monitor
Pros
- Includes 22-inch 1080p 75Hz monitor
- RGB keyboard, mouse, and speaker included
- 16GB RAM and 2TB HDD for ample storage
- Plug-and-play simplicity
Cons
- Uses 3rd-gen Core i5, very old
- No SSD, slower boot times
- Integrated graphics only
Best for: a first desktop for a young child who needs everything in one box.
This bundle is the easiest to get up and running: desktop, monitor, keyboard, mouse, and speaker all in one shipment. The 22-inch 1080p monitor has a 75Hz refresh rate, which is better than a standard 60Hz office panel for Roblox. The Intel Core i5 (3rd Gen, Ivy Bridge) is old and slow by modern standards, but Roblox itself is not demanding. You can play the game at low settings at 1080p without major issues.
The 2TB hard drive is enormous for a budget machine. That is room for hundreds of games, movies, and music. The absence of an SSD hurts, booting takes over a minute, but you can swap the HDD for an SSD with a simple clone. The RGB peripherals are basic but functional; the keyboard has blue, red, and green backlighting.
For a six-year-old who just wants to play Adopt Me and dress up their avatar, this desktop is fine. The total cost is among the lowest, and the included monitor means you do not have to raid your own setup. The processor will bottleneck any attempt to upgrade the GPU later, so consider this a starter machine that will be replaced when the child outgrows it.
9. HP Elite Desktop Bundle: Best Value Bundle
Pros
- Complete bundle with monitor, keyboard, mouse, speaker
- 16GB RAM and 1TB HDD
- Office-style design looks professional
- Reliable HP hardware
Cons
- Old CPU generation (Ivy Bridge again)
- Integrated graphics
- 1TB HDD, no SSD
Best for: a home office that doubles as a kids' Roblox computer.
The HP Elite bundle mirrors the Dell OptiPlex bundle above but with HP hardware. The specifications are similar: a 3rd-generation Core i5, 16GB RAM, 1TB HDD, and a 22-inch 1080p 75Hz monitor. The peripherals are RGB, though the speaker is notably small. For Roblox, integrated graphics suffice for low settings; do not expect to run Roblox Studio and play at the same time.
HP's Elite desktops are built to corporate standards, so they are durable and quiet. This bundle is ideal for a household where the computer sits in a common area, used for homework by day and Roblox by night. The monitor has VESA mount holes if you want to wall-mount it later.
The biggest drawback is the slow hard drive. Loading Roblox takes 30-40 seconds, and Windows boot times are similar. An SSD upgrade would cost about $20 and transform responsiveness. If you are willing to do that, this bundle becomes an incredible value machine.
10. Dell OptiPlex 7010 Bundle: Cheapest Desktop
Pros
- Costs less than most gaming chairs
- Includes 19-inch monitor, keyboard, mouse
- DVD drive for old games or movies
- Works fine for basic Roblox play
Cons
- Only 8GB RAM
- 500GB HDD is modest
- 19-inch monitor at 1366x768 resolution
- Very old platform (3rd-gen i5)
Best for: the absolute cheapest way to put a Roblox-capable computer in front of a kid.
The OptiPlex 7010 bundle is the bargain basement of this roundup. It uses a 3rd-generation Core i5 (Ivy Bridge), 8GB RAM, and a 500GB hard drive. The included monitor is 19 inches at 1366x768 resolution, which is lower than 1080p. For Roblox, that lower resolution is actually a benefit: the integrated Intel HD 2500 can handle the game at native resolution without too much trouble. Expect medium settings at around 30-40fps.
8GB of RAM is enough for Roblox alone, but not for multitasking. If Discord, Chrome, and Roblox are all open, you will feel the slowdown. The 500GB HDD fills up quickly too. This machine is strictly for solo play, not streaming or recording.
The included DVD drive is a relic but fun for a young child who might buy a physical Roblox game or an old PC title. For the price, this is a working computer that plays Roblox. It is hard to argue with that if your budget is extremely tight. Just know that you will likely want to upgrade within a year or two.
How to Choose a Desktop Computer for Roblox
Roblox is deceptive: it looks like a simple blocky game, but its rendering engine has evolved considerably. Choosing the right desktop comes down to four factors.
CPU Single-Core Performance
Roblox runs on a single main thread for most of its game logic. That means a processor with high clock speed and good per-core performance matters more than many cores. Intel Core i5 from the 8th generation or newer, or AMD Ryzen 5 from the 3000 series or later, will give you smooth frame rates. Older CPUs like the 3rd-gen i5 can still play the game, but you may need to lower graphics settings.
Dedicated Graphics vs. Integrated
Integrated graphics (Intel UHD 630, HD 2500, etc.) can run Roblox, but usually at low to medium settings. A dedicated GPU like the Radeon RX 580 or RX 6500 XT unlocks max graphics and consistent 60fps, even in crowded servers. If your child plays competitive obbies or builds in Roblox Studio, a dedicated GPU is worth the investment. If they only play casual games, integrated is fine.
RAM and Storage
Roblox itself uses about 2GB of RAM, but modern Windows 11 wants 4-6GB just to idle. 8GB is the bare minimum; 16GB is comfortable for light multitasking. For storage, an SSD makes Roblox load in seconds rather than minutes. Even a budget SSD upgrade transforms an old office PC into a responsive gaming machine. Hard drives are still common in renewed desktops but plan to swap one in eventually.
Upgradeability
A desktop with a standard form factor (like a Dell OptiPlex Mini Tower or a mid-tower ATX case) allows you to add a graphics card later. Small form factor (SFF) systems may require low-profile GPUs, and some do not accept any expansion. If you want a machine that grows with your child, choose a model with a PCIe 16x slot and a power supply that can support a 75W card without changes.
The most important rule? Match the desktop to how the machine will be used today, not to the maximum Roblox settings you dream about. A cheap renewed OptiPlex with an SSD swap plays Roblox just fine for a younger kid, while a teen who builds experiences needs the Ryzen 5 and a discrete GPU.
Frequently Asked Questions
Can any computer run Roblox?
Yes, most modern computers can run Roblox at some quality level. The minimum system requirements are a processor with 1.6GHz or faster, 1GB of system RAM, and DirectX 10 or higher graphics hardware. However, to enjoy the game at a stable 60fps with decent visuals, you should aim for a desktop with a dedicated graphics card and at least 8GB of RAM.
Is Roblox more demanding on CPU or GPU?
Roblox is mostly CPU-bound in most scenarios. The game's physics and scripting run on the main thread, so a processor with strong single-core performance is beneficial. Graphics load increases with high settings and anti-aliasing, but even a mid-range GPU is overkill. For Roblox Studio (the creation environment), the GPU becomes more important for real-time rendering.
Do I need a gaming desktop for Roblox?
Not necessarily. Many renewed business desktops (like the Dell OptiPlex models in this roundup) run Roblox well when paired with a low-profile GPU. If you are only playing casual games like Adopt Me or Royale High, integrated graphics and 8GB RAM are enough. If you want to play at max graphics or stream, a dedicated GPU helps.
How much RAM do I need for Roblox?
8GB is the minimum comfortable amount for running Roblox and a few browser tabs. 16GB is the sweet spot for simultaneous Discord, Chrome, Spotify, and Roblox. 32GB is only necessary if you are also running virtual machines or Roblox Studio with heavy asset packs.
Can a renewed office PC be upgraded for Roblox?
Yes, most mid-tower and mini-tower office PCs have a PCIe x16 slot that can accept a low-power graphics card like a GTX 1650, RX 6400, or RTX 3050. These cards draw power from the slot and often fit in small cases. Check the power supply wattage: 250W or more is usually enough for a 75W card. Before buying a used office PC, confirm it has the slot and PSU capacity.
Should I buy a new desktop or a renewed one for my child?
If your budget allows, a new desktop (like the STGAubron or LXZ) comes with a warranty and modern features like Wi-Fi 6 and NVMe SSDs. Renewed office PCs are cheaper, but the hardware is older and may lack compatibility with the latest Windows updates or Roblox features. A renewed machine is a great choice if you are comfortable replacing the hard drive with an SSD and possibly adding a GPU.
What about mini PCs?
Small form factor computers are not ideal for gaming because they typically lack a slot for a dedicated graphics card and have limited cooling. Some mini PCs with AMD Ryzen 7 APUs (integrated Radeon graphics) can play Roblox well, but they cost as much as a full-sized gaming PC. If you are considering a mini PC for a small desk, think about how it fits with the options from our roundup for best mini pc for gaming instead.
The Bottom Line
The best desktop computer for Roblox is the STGAubron gaming PC, because it combines a genuine dedicated GPU, enough RAM, and a fast SSD at a price that leaves room for a good monitor. The older i7 CPU is not ideal for heavy multitasking, but for Roblox and most casual gaming it is plenty.
If you need to spend less, the WIWB Ryzen 5 desktop or the LXZ alternative offer a newer platform with a modern six-core CPU, even if the GPU has less VRAM. For the absolute minimum budget, any of the renewed Dell or HP bundles will run the game if you add a cheap graphics card. A child does not need a $1, 000 machine to enjoy Roblox. What they need is a computer that loads the game fast and does not stutter when their friend builds a giant roller coaster. The picks above all do that, and the right one depends on how you plan to play.
