Our top pick for the best RTX 4090 Gaming PC is the ABS Eurus Aqua RTX 4090 Gaming PC. It’s a smart build utilizing a top tier pairing of the 14900KS alongside the RTX 4090 for incredible speed and power. It’s well priced too.

How we picked our best RTX 4090 gaming PCs in 2024

These gaming PCs are some of the most expensive around and are serious investments. For many, we’d say they are overkill, but for those looking to go all in, they’re certainly worth considering. In terms of pricing, you’ll find a bit of a range depending on what other components come with the PC itself. Lower-priced models may have older CPUs, less RAM, and a smaller SSD, while more premium options tend to have the latest processors, advanced cooling, latest RAM, and massive M.2 SSDs, alongside stunning cases that show them all off.

Naturally, we’ve researched and selected our best RTX 4090 gaming PCs based on a number of factors, such as components, value for money, design, and anything else we thought made them stand out from the crowd. Of course, we’ve reviewed the RTX 4090 ourselves, so we know it very well from hands-on testing. We also know exactly what it requires from its neighboring components to help make it tick – and so what comprises a top pick. 

For this list, we’ve included a range of options based on a variety of processors and prices. We regularly update our selections to ensure you’re getting the latest and greatest, so be sure to check back in with us in the future as the selections in this list may change. That also means there may be a better RTX 4090 prebuilt option for you a little down the road. 

Best RTX 4090 Gaming PC
  • High-end ABS Eurus Aqua gaming PC with RTX 4090, RGB lighting, and visible components through a glass side panel.
  • A gaming PC tower computer case with a transparent side panel displaying rgb-lit fans, powered by the Eurus Aqua RTX 4090.
Best in Class
  • CPU: Core i9 14900KS
  • GPU: RTX 4090
  • RAM: 64GB DDR5
  • Storage: 2TB NVMe SSD
What We Think

A great option for pure performance, featuring top tier components from the RTX 40-series and 14th gen era.

Reasons to Buy
  • Includes Core-i9 14900KS for top tier performance
  • Offers huge 64GB 6000MHz DDR5 RAM
  • Lower price than other systems with less powerful components
Reasons to Avoid
  • Doesn’t come with a keyboard and mouse
  • 2TB SSD is fine for most but less than in other systems

If you want the very best combination of components in an RTX 4090 gaming PC then you’ll want the best of all CPUs – step forward the ABS Eurus Aqua RTX 4090 system. 

This PC features the incredibly quick Core i9-14900KS, alongside an Nvidia GeForce RTX 4090 GPU 24 GB, 64GB DDR5 6000MHz RAM, and a 2TB SSD. That’s quite the collection of components, and only slightly lacking if you want ample storage. 2TB is more than enough for most users though – unless you’re a content creator or otherwise require large amounts of drive space.

…an i9 14900KS CPU paired with the 4090 is the pinnacle of performance in gaming PCs as of the 14th gen era…

PC Guide

Let’s face it though, an i9 14900KS CPU paired with the 4090 is the pinnacle of performance in gaming PCs as of the 14th gen era, and there’s nothing this PC won’t be able to handle in multi-tasking, gaming, streaming, or editing functions. This PC does have a more understated appearance which will be better for those who prefer performance over appearance, but there is RGB support throughout, and a tempered glass side panel to help show off the core of the system.

The most impressive thing here though is the price, as this Advance Battle Stations Eurus Aqua system comes in at a similar price we’ve seen for systems lacking the pairing of 4090 and 14900KS. This system may not have additional features like a mouse or keyboard – you’ll need your own – and it may lack for some in storage. But otherwise, it’s a top-tier option. 

What users say

Owners of the ABS Eurus Aqua RTX 4090 prebuilt on Amazon have commented on just how well the PC works straight out of the box, stating it “Worked great right out of the box”, and that it’s an “Amazingly built gaming PC, everything comes built and it fires up just as it should”. Value was also a popular feature, with multiple buyers sharing that they think “This is a very powerful machine considering the lower price”, and that they’re “still trying to find out why this thing is so cheap and arrived so quickly”.

However, one caveat that came up was the size of the 4090 itself – it’s a powerful card, and this is obvious from how big it is. So, users have recommended that you “buy a support for the graphics card due to the large size and the risk of the graphics card sagging and damaging the pricey part.”

Best Budget RTX 4090 Gaming PC
  • A MPG Velox gaming desktop pc case with blue led fans.
  • An MPG Velox Gaming Desktop case with a tempered glass side panel and illuminated blue fans.
  • Close-up of an MPG Velox MSI Gaming Desktop with RGB lighting and a visible cooling fan through a transparent panel.
  • CPU: Core i7-11700F
  • GPU: RTX 4090
  • RAM: 32GB DDR4
  • Storage: 512GB NVMe SSD + 3TB HDD
What We Think

A strong option if you have less to spend – the i7 11700F is till a capable processor, and will keep your system ticking for a while yet. Do bear in mind that the only future upgrades available CPU wise are more powerful 11th-gen options.

You won’t really find a budget RTX 4090 gaming PC, but you can find slightly more affordable options on the market that pack a punch – like the MPG Velox by MSI.

This gaming PC is built with an i7-11700F CPU, Nvidia GeForce RTX 4090 GPU 24 GB, 32GB DDR4 RAM, 512 GB SSD, and 3 TB HDD. Now while that’s not as maxed out as some of the other prebuilds on this list, it will still deliver when it comes to performance. The i7 CPU coupled with 4090 graphics can breeze through practically everything, gaming, multitasking, streaming, and more.

PC Guide

One area it is slightly lacking is the case itself, however does have LEDs and RGB fans that can be customized through the app. It also comes with a wired backlit gaming keyboard and mouse, which is great if you want to dive right in out of the box – but ultimately we’d recommend swapping out with something a little more tailored to your needs. 

Overall, as far as affordability goes when it comes to RTX 4090 gaming PCs, this MPG Velox does hold some appeal. However, if you’re after the very latest components to go alongside your powerful graphics card, such as DDR5 RAM, a larger SSD, or a 13th Gen Intel CPU, you may find what you’re looking for by increasing your budget.

  • RAM: 64GB RGB DDR5 Memory

Corsair is well-regarded for a reason and this system is well specced and well put together. If you want iCue and the RGB control that comes with then definitely the option to go for. If not, then less so and there are better choices here – like the Skytech system.

Reasons to Buy

PC Guide

Overall, as far as RTX 4090 gaming PCs go, we think this one has a lot going for it. Sure, it’s pricey, but if considering the qualify of all the components, we think it’s actually solid value for money.

Things to consider when buying an RTX 4090 gaming PC

If you’re on the hunt for an RTX 4090 gaming PC, you’ll want to factor in a few things before making your purchase, especially as these are some of the priciest gaming PCs on the market.

Is an RTX 4090 gaming PC overkill?

It may sound obvious, but RTX 4090 GPUs are actually pretty overkill for most people. We’d say the best candidate for an RTX 4090 gaming PC is someone who uses it for playing AAA games at the very highest settings possible, someone who works in 3D rendering, or someone who is a mid-pro level streamer or competitive gamer. If you meet the requirements, great! But if not, we’d recommend going for something less powerful that will ultimately save you money, and be more appropriate for your needs.

How much should you spend on an RTX 4090 prebuilt gaming PC?

You’re looking at anywhere between $2500 to around $4500 from what we’ve come across, however, you may find some options lower if they are pre-owned or higher if they pack the absolute latest components or have something unique about them. At the lower end, you’ll come across gaming PCs that have older-generation CPUs, not as much RAM, and smaller SSDs. At the higher end, you’ll find the latest CPUs, loads of DDR5 RAM, massive SSDs, and also more visually impacting cases and lighting.

Is it worth getting an RTX 4090 gaming PC now?

Now is as good a time as any in our opinion. RTX 4090 gaming PCs are still the very best and we’re not expecting the 50-series options in the future to make them obsolete by any measure.
