The motherboard choice also has a massive effect on the performance of CF or SLI.

The only real way to get 2.0times the performance, on any set of cards, is to have a motherboard that supports dual (or tripple on some) x16 pcie, and I beleive the only readily available motherboards that support that are the i7 boards....

Am I correct or just regurgitating bad info?
IIRC the 680 and 780 nvidia chipsets all support dual 16x SLI.

Crossfire 16/16 support is given on the /X38 (with PCIE 1.0 however) and (P45? Unsure) X48 (PCI2.0)
