One, thing interesting to note, I am judging this off of 4 people I know who have the game and the other people who have posted their video cards.

Ati seems to not get as hot as nvidia with this game. As only computer had any issues was my moms nvidia 6800GT which solution was getting rid of the very old graphics controller drivers she was running. I am currios if anyone has ATI cards that are over heating. Reason yes is to judge software relation as well ATI and nvidia really do read things differently alot of times.
