I gonna be buying a new system soon, im looking at getting the Asus P5N32-E SLI which uses the 680i sli chipset. I'm wondering if i can run dual ati cards on it in crossfire? or at leats a single ati card? cos im proly gonna be getting a G80 or a R600. Ill be buying in mid april so new G80's and the R600 should be out.
