Most interest in these cards SLI'ed that I've seen is leaning towards surround gaming- which requires two (or more cards) since nVidia cards can only support two monitors each. Just as a side note....Regarding GTX400's stacked in consecutive PCIe x16 slots on a board, I, like nVidia wouldn't recommend the practice. Using a bog-standard P6T is a great way to inflate temps -not that the cards need any encouragement in that area. I think I'd be looking at a board that can seperate it's two primary graphics slots with at least two PCI/PCIex1/blank slots, such as the P6T Deluxe/P6TD, P6T6 WS, P6T7 WS, R3E, M3E, P7P55D/P7P55D-E Deluxe/Premium or Sabertooth i55 when it comes to Asus products (amongst others I'm sure).
