    PCI Express - backward compatible?

    It seems my video card, a GeForce 7300GS has died. My motherboard manufacturer told me that the PCI-E slots on the board are v1. The motherboard is an EVGA nForce 590SLI. I'm having a hard time finding an older video card with v1 PCI. Can I use a more up-to-date v2 or v3 video card in this motherboard? In other words, is the PCI spec backwards compatible?

    Officially, yes, and it usually works. I do have a board with a ULI chipset that doesn't like PCIe 2 cards.

    It will/should work. I have had to do the same thing, but some performance will be lost, though I didn't really notice.
