I'm looking to get well-performing gaming desktop since my old one finally pretty much died. I'm just looking for suggestions since I'm illiterate when it comes to newer computer hardware. I plan on using the desktop almost exclusively for smooth gaming, including emulation. I want to be able to run up to PS2 games without too much of a hassle. Other games that will probably be played on it include every single version of the Sims, and most likely Minecraft. So I think I want to aim for 8GB RAM, but I know it doesn't mean shit without a good video card. My budget is roughly $700. What else should I look for? Anyone know any decent video cards I should look out for?
