ok i need some advice, right now i have a 7800gtx, but i want a 7900gtx. but looking at benchmarks 7800gtx in sli beats the 7900gtx in 3dmark05 by 1000 points and 500 in 06. now do you think i should get another 7800gtx and wait for the g80 cards to come out this summer or should i buy a 7900gtx and then get another one for sli this summer when the price drops (due to the g80 coming out). im in a pickle what should i do?
