That's a Crossfire board. I believe that you'd have to hack the Nvidia drivers to get that to work in SLI. It would probably be very buggy if somebody got it to work, and Nvidia wants you to buy an Nvidia based board so they can make a bit more money, so I doubt that they will hack an Intel based board to work with SLI. A long time ago I read a review of an attempt by either VIA or SIS to make SLI available on one of their chipsets. It did work, but it was buggy, and the video driver had to be provided by VIA or SIS, so it had limited compatability with games.
