The motherboard choice also has a massive effect on the performance of CF or SLI. Your performance at x8x8 wont necessarily be twice that of the original card because the pcie slot on one card will run at x16.... it'll more less be like 1.75-1.8 time the performance.... correct? 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?
