    I have A ASUS A8N-SLI Deluxe motherboard socket 939 which is a PCI Express v1.0. Will A PCI Express v2.0 Video Card (HD4870, HD4850 is what I want to buy) work on v1.0?

    Yes it will and with minimal (probablly not noticable) performance loss.:)
    X-Terminator says thanks.

    At X16 lanes, no, there won't be any impact on the performance. However, make sure you have a good power-supply for the card as PCI-E 1.1 doesn't supply power on-par with PCI-E 2.0.

    It won't matter, either way the card is sucking up the same amount of power from the PSU. You don't need a better one just because you are using PCI-E 1.1.

    I have an ASUS M2NPV-VM, socket AM2 that supports PCI-E 1.0, and my PCI-E 2.0 HD3850 works fine on it.

    The HD4850 seems to draw about 33W from the PCIe slot and the rest off the PCIe connector. (Rightmost diagram). So powerwise it's just fine.
