Generally speaking, building a PC will initially be more expensive. In the long run, however, you'll save money because it's less likely you'll need to replace components, and, if you do need to, they're easier to fix.

By choosing your components carefully, you can build an incredible gaming rig for less than 500 bucks. While it won't perform as well as higher-end gaming PCs, it can still deliver incredible graphics and great performance. Budget gaming rigs are best for average games.
