im going to use 2560x1600

you dont have to upgrade ery time there is a new gen of Graphics Cards come out :)

my budget is 4000USD

i guess your right

yes u are right it scale better from 1-2 then 2-3, but it is very different how good different games use 2 way sli and 3 way sli some games even run 2 way sli better than 3 way sli, but i want to make my build more future proof cause the newer games will be better to use 3 way sli which will give a higher frame rate :D

i found some bencmarks on 3x660ti's they could run metro 2033 on ultra settings in a average of 84.2 fps! :D

yes u could Overclock GTX 670 to GTX 680 lvl but u can overclock GTX 680 into higher performence to

what's best im starting a new and I would like to discuss what is best
