hello everyone, i have been look around to see if i could figure this out and i semi got an answer but im trying to be certain before i go out and buy anything. What i am wondering is could i run a PC 8800gt in my older mac pro only under windows xp. i dont care about OS X because i will keep my 7300 for that. If anyone can help me it would be greatly appreciated. Also if the 8800 wont work would the 8600 work? thanks again
