a friend of me wanted to buy a graphics card, he knows some friend with older cards to be sold, as they are upgrading, he now has 8600gt and wants to upgrade to one of the following cards, 9600gt 512mb or 8800gts 640mb, both at the same price, from what i know 9600gt has a slight edge over the 8800gts, and 8800gts 320/640mb is comparable to 9600gso, i want to be sure is this correct or both 9600gt and 8800gts has the same performance, if anyone has a link of comparison please send it here ...
