Can PCI-E Lanes affect graphics card performance?

So I'm considering buying an older motherboard. Specifically the Intel Desktop Board DQ67EP, but upon researching the specifications I see the board has a Max # of PCI-E Lanes of 1. I dont think I have ever seen a board with so few PCI-E Lanes or have any idea what this means for performance on the slot. I would mainly like to know if I throw in my GTX 1060 if there will be a decrease in performance because of 1 available lane. Thanks for the responses

  1. From what I can see http://ark.intel.com/products/51998/Intel-Desktop-Board-DQ67EP it has 16 PCI-E 2.0 lanes. It's an older PCI-E spec but it should be fine.

    Right but if you scroll down to the Expansion options it says "Max # of PCI Express lanes" 1. However thats just the system bus, The CPU yes should provide 16 PCIe 2.0 lanes which go to that GPU slot.

    EDIT: and I wanted to point out, doesn't really make sense the Q67 should have 8 PCIe lanes, but maybe the SATA ports and other system devices take up some, however that board only has a GPU slot so it doesn't really matter anyway.
  3. Weird, never seen that before.
