    Does a pci express 2.0 video card function correctly on a pci express 1.1(?) x16 motherboard?

    thanks

    ah, thanks :)

    But for example, If I put a 2.0 card in a 1.1 motherboard, would the card be half as fast?

    i can't actually find out, but, it is reasonable to assume that a PCIe 2.0 card would only function @ the mobo maximum PCIe 1.1 speed of 0.25 Gbyte/s

    Edit:
    yes

    On that, and i know i'm a little late, but PCIe 1.1 has a WHOLE LOT of bandwidth, not saying 2.0 is not worth anyones time, but i doubt you'll see any real performance issues.
