  1. Best answer
    It will still work; I run a 660 Ti (PCIe 3.0) on a mobo that only supports PCIe 2.0 and it works perfectly. The transfer rate on the bus is a bit slower, but the card still functions well.
  2. It wont make a difference. PCIe 2 and 3 are compatible, and in terms of GPU's where slot bandwidth is greater than 4x, it doesnt matter.
  3. thanks
    i will buy the 660oc
