I have read articles on the mobo's usin the 680i chipset, such as the asus striker and Asus P5N32-E (i'm sure there are others, just i'm an asus fan), and they hint at a third video card runnin on the third pci-e slot, saying that it could make use as something like a physics processor. I can't find any articles on three video cards, just on 2 like the SLI and crossfire configurations. Anybody have 3, if so, any gains on such a setup?
