no OS bud? and im talking a rig that runs as well as a ps3 i honestly dont know much about the 4670 but is it really as good a the consol gpu? plus no cpu cooling, ps3 has a bluray drive so simple dvd player wont do it. cpu fine, AND this is all assuming you have a monitor/tv for HD.
We're only talking about their ability to play games. Anything the PS3 can do that the PC can't is easily outweighed by what the PC can and the PS3 can't.
