Whats the average you would spend on a gaming computer and would you rather buy it complete or build it yourself? I was looking at a 500gb hd with 4 gb ram and an nVidia 8600gt graphics card. Since the guy took the listing down since I said I would buy it (for $400) that is just what I can remember off the top of my head but what are your thoughts ns? Any solid companies that sell good gaming computers?
