    What's better?

    Is my MOBO compatible with pci-e vid cards?

    No, you mobo does not support PCI-e, 'only' AGP.

    PCI-e is the way forward as it allows much faster data transfer. It is basically the future interface for g cards. Saying that, AGP is still not dead. So if you are looking ahead and looking for a new board, there is hardly any point going for an AGP board.

    PCIe comes in 3 flavors of slots: x1, x4, and x16. The number indicates the amount of PCIe lanes linked to it at full capacity.

    PCIe's versatility is such that it's set to replace PCI, PCI-X, and AGP in one swoop. Unlike the other formats I've mentioned, PCIe's design is serial, while everything else is parallel. Parallel designs allow for sharing the entire bandwidth among the devices plugged into it. It's a problem for storage, networking, and graphics. Devices of serial nature don't have to share. Each PCIe lane is 250MB/s up and down, for a total of 500MB/s---again, per lane.

    PCIe and AGP are incompatible, like it is with PCI and PCI-X.

    VIA and ULi both had chipsets with native AGP and PCIe support, but they never caught on unfortunately...and nVidia bought out ULi. Outside of these rarities, if you happen to run across a motherboard sporting PCIe and AGP, be warned that the AGP slot is most likely a hack job into the PCI bus which will limit your video card to the paltry 133MB/s

    This bring to a new question. Will a Crossfire video card obviously from ATI work on a SLI mother board and can you put to Crossfire Video card in a SLI motherboard?
    the reason for this question is that i read in the Neweggs website reviews, some one saying to someone else that wrote on his spec of system that he had two Crossfire video card in a SLI motherboard and that it was working fine and that that was not true and Crossfire video card wuold not work in a SLI motherboard. Could that be true?
