my rig is a bit better than the one stated in the article but can run supreme commander (all settings on as low as possible of course) pretty darn well
core2 6400 @ 2.37ghz (i have a crap mobo)
1.5GB DDRI
6600GT
a faster cpu could well give that 6600GT a bit more life
dont get me wrong though. i cant wait to get a new graphics card. this one has certainly over stayed its welcome
