From some of the best budget gaming PCs to maxed out ones with an Intel Comet Lake or AMD Ryzen 5000 chip and an Nvidia Turing or Big Navi inside, these belong at the top of the pile. When coupled with the best gaming monitor, they are the stuff of legends.

Intel’s NUC has come a long way from its humble beginnings. For example, while the previous Hades Canyon didn’t come with a RAM or storage, the newer Ghost Canyon has both. In fact, not only does it have more offerings now in terms of specs, but it’s also highly configurable so you can personalize it to your liking before hitting that buy button. With 9th-generation Intel Core chips, up to 64GB of memory and up to 4TB dual storage, we’re all for it. The only catch is that it's pricier now as well. The lower configurations are still quite affordable, and the best gaming PC for the budget- and portability-conscious. However, you may want to stay away from the highest configurations.
