So now all i need is a motherboard and my question is running those two 690's(quad sli) on 8x/8x PCI will I notice any loss in performance? or should I be looking for a board with PLX chip that allows 16x/16x SLI?
Because atm I'm inclined to buy the Asus Maximus V formula wich only supports a 8x/8x while other boards such as the sniper 3 from gigabyte support 16x/16x.
There's no more than 1% difference in pcie 3.0 x16 and x8 but then again the cards tested were the 7970 and 680. There could barely be a difference between x16 and x8 with the 690 but if I were you I would get a board with x16 / x16 just to be positive that I'm getting the most out of these cards.
