November 14, 201015 yr I have a gigabyte motherboard with 1 PCIE-X16 video slot and 1 PCIE-X8 video slot. CPU is E8400. Card is ATI 4890. The manual states if you are using 1 video card place it in the X16 slot. That is where it is. The 2nd video card goes in the X8 slot. With 2 video cards the manual says that the 1st video card will then operate up to X8 only. I want to go to 3 monitors. Other then the degradation from 3 monitors, does this 2nd video card then degrade performance?JimCYWG
