I have an am2+/am3 ready motherboard but crossfire capable.. its said that my motherboard supports 2.0 pcie. I have a question.. do I need to change my motherboard that supports pcie 3.0? I am planning my computer to be a gaming rig.. do I need to change my mobo? or 2 videocard to be crossfire is ok? than new motherboard that has single pcie 3.0 slot? I hope that my questions will be entertained here..
Crossfire is independent of the PCIe revision. PCIe 3.0 allows for more bandwidth, which is great, but having PCIe 2.0 spec'd hardware won't inhibit you at this point in time. Last I knew, the most powerful video cards weren't tapping out the PCIe bandwidth with 2.0 hardware, so you'll be fine. As long as your motherboard supports Crossfire, you'll be fine. If it doesn't, then yes, you'll need a new motherboard.
