Hello, Finally I get to upgrade from my 6800Ultra pci-e 256 mb... But I dont know what to do. Would you guys help me out ? 8800ultra? or 8800GT? or GTS?? Whats the best 8800 right at this moment? I want to buy the best so I wont bother upgrading in A LONGGGG time just like I did with my 6800ultra. Best graphics Ive ever had up to this moment. Thanks !!
