I'm curious to find out if the 4 GPU support of the 4, 16x PCIe 2.0 slots on this board includes the use of 2-chip cards. The GeForce GTX 295 claims to support Quad-SLI.
I'm going to see if I can get one set up at work. Supermicro does have a barebones config with a very nice case and a 1400 Watt PS.
