If I were to purchase a motherboard with 7 pci-ex ports. Could I then attach 7 graphic cards and run 7 cgminer processes? One for each card?
Or would a better build be to group cards together with SLI/Crossfire?
If one of these cards generally gives 1200mhash, would i be correct to assume that 7 would give me 8400? Or is there some overhead issue here I'm not aware of?
