I would like to run these cards but they would be super close in the normal pcies. Would it even fit? Could i run the second in the lowest slot and what kind of affect would that have on my bandwidth/performance?
you would have to run the cards in pci-e slot 1 and 3, 1 and 4, and 2 and 4, your motherboard manual will tell you which to use. some of the slots will probably be x16 x8 or x4. try and get both video cards into x16 slots, but x8 is just as good.
