According to Steam:My graphics card is a ATI 5750.
It takes a few days to get use to the controls, then once you get a hold of the controls you be learning new tactics after every battle. Campaign sucks, Skirmish and Multiplayer is fun. The Skirmish AI adapts fast.
Aww. Once again, mine is a 3200, so it's pretty low, damn.
wait, that's the Mac, the PC one is ATI RADEON X1800 GTO, I've never heard of it, but I guess it's no different to Mac.
