i think the reason my vid card is so crappy is cuz of overheating. i.e. i play cs fine for the first 5-10 min then after that i assume the heat got to it then it cause the color to be weird. the ground would sometime look liek a checker board. im planning to buy a expansion slot fan and was wondering where do i hook it up to. and is there a way to find out if heat is really the source of my prob then just to play games w/o the case on?
