I am looking to run an i7-2700k, with the ASUS p8p67 pro rev. 3.1 and i am buying one video card immediately and i would like to buy a second in the future and i am wondering if that model asus will be able to house/support the two video cards?
Its a great board indeed, I have one. It supports SLI and Crossfire both, but it is 16x if you use one card, and 8x/8x if you use 2 cards. Although 8x/8x bandwidth is plenty for 2 cards in all but extreme cases, and even then the benefit is still very small, some people prefer to spend a little more and get a board that supports 2 cards at 16x/16x.
