I just got my Asus SLI mobo today. I took many of components from previous computer and got it working today.
Specs below.
Unfortuately, eVGA won't sell me any more 6800 ultras as they are on backorder.
And I heard from Nvidia that you have to use the same brand and model for SLI, so I'm stuck with one meager 6800 ultra until i can get another.
I so happy that i got my sli mobo and so pissed that i can't test it out.
