Gaming PCs live and die by their graphics cards (or graphics chips, in the case of gaming laptops), the most critical PC component for determining your gaming performance ceiling. Most gaming systems will come preinstalled with a single midrange or high-end graphics card; higher-priced systems will naturally have better cards, since purchase price typically correlates with frame-rate performance and visual quality. AMD and Nvidia make the graphics processors, or GPUs, that go into these cards, which are made by third parties such as Asus, Gigabyte, MSI, PowerColor, Sapphire, and XFX (to name just a few).

Gone are the days of complicated dual-card setups: Today's top-end GPUs, like the Nvidia GeForce RTX 4080, GeForce RTX 4090, GeForce RTX 5080, and GeForce RTX 5090 are more than powerful enough on their own. Games are increasingly developed to take advantage of the cutting-edge features available in single GPUs like these, but these premium cards will cost you. A tier of less-expensive GPUs in the GeForce RTX 50 series, fortunately, is also available for smaller budgets; you can find a full breakdown below.

Still, you should divert as much of your budget to the best GPU you can afford; the most pivotal decision you'll make when purchasing a gaming desktop is which card you get. Of course, one option is opting for no card at all; the integrated graphics silicon on some modern Intel Core and AMD Ryzen processors is adequate for casual 2D and very light 3D gaming. However, to reliably play 3D AAA titles, you need a discrete graphics card, and these cards are what distinguish a gaming desktop from "just a desktop."

Whether you go with an AMD- or Nvidia-based card is based partly on price and performance. Some games are optimized for one type of card or another, but for the most part, you should choose the card that best fits within your budget. If you're buying a complete gaming desktop, you (of course) don't have to pay for a card in isolation, but this should help you understand how the card factors into the total price. You also have to know what you're shopping for.

If you've made it this far, we trust you're more prepared than ever! In our review summaries and spec comparison chart, we've outlined the best gaming desktops we've tested recently. Some are configured-to-order PCs from boutique manufacturers, but others are from bigger brands typically associated with consumer-grade desktops. Note that many of the same manufacturers also make gaming laptops if you're choosing between the two.

Equipping your system with any high-end GPU will boost your total PC bill by a few hundred dollars. Beyond adding extra power to your gaming experience, some graphics cards can power up to four displays, though few gamers go beyond two or three (and even then, only rarely).

In the long run, a better reason to opt for high-end graphics is to power 4K gaming and virtual reality (VR) experiences. Monitors with 4K resolution (3,840 by 2,160 pixels) and the displays built into the latest VR headsets have much higher pixel counts than a "simple" 1080p HD monitor. You'll need a decidedly high-end graphics card to drive a 4K display at the highest quality settings. If you mean to play games on a 4K panel with detail settings cranked up, you'll want to look at one of Nvidia's highest-end cards suited for 4K play, with the RTX 4080, RTX 4080 Super, RTX 4090, RTX 5080, and RTX 5090 easily the best picks. An AMD card in its Radeon RX 7900 series could work, too.

Selecting a graphics card for VR is a different set of considerations and not quite as demanding as 4K play on recent AAA games. VR headsets have their own graphics requirements. Generally, a GeForce GTX 1660 Ti or a Radeon RX 5600 XT/RX 6700 (or higher, in either case) should suffice as the floor for VR. Naturally, more demanding VR games will benefit from superior GPUs. Look at the recommended minimum GPU specs for your specific VR headset and exceed them by at least a small margin to guarantee smooth performance.

Know, though, that 4K gaming is unquestionably a higher-end pursuit than VR, from a resource POV. You can still get a rich gaming experience for thousands of bucks less by choosing a desktop with a single but robust middle-tier video card (an RTX 5060 or 5070, for example) and gaming at 1080p or 1440p; 2,560 by 1,440 pixels is an increasingly popular native resolution for gaming monitors. If you're less concerned about turning up all the eye candy found in games—anti-aliasing and esoteric lighting effects, for example—then today's less-powerful graphics cards and GPUs will still give you plenty of 1080p oomph for much less money than an elite card.
