I'm looking to buy a new desktop computer (I don't like laptops).?

I would do what Proto says as it's very easy to install a video card yourself. Jimmymae has a fairly good idea but the video card in his suggestion is quite weak for gaming. His video card has 48 stream processors and Proto's pc has 400. You can click my avatar to email me for how to install a video card, I have done many and it's easy.
