if you are going to sli, get the cheaper 7900gs and overclock them. no sli, get the 7950gt. of course, if you are going to buy two new 7900gs's, you might as well buy and 8800gts 320mb it will cost roughly the same as 2 7900gs cards. and perform a little better maybe, but i am not sure if the 320mb outdoes 2 7900gs or not.
I guess that would be the question then.. I was thinking this earlier, if I was orginally going to drop $300 on two cards would they perform better in sli mode than one card that could be purchased for the same cost?
Does anyone have this answer?
