Good computer for gaming?

Actually, one of my best friends has a similar custom computer he made, only difference is he runs a NVIDIA video card , just because we prefer them. But i haven't heard anything really bad about radeon, but its really all just opinion/preference. Yes for the most part this set up would let you play some of the latest games , the only thing i would suggest changing is definitely ram, but for the most part it is a pretty good deal $$$ wise and just quality wise. :)
