    This board has one PCI-E 2.0 x16 and one PCI_E x4 slots. Would cross-firing 2 HD3870's be a waste on this board? I'm thinking I may have to dump this board for the 790 chipset.

    Well it wouldn't be waste. If you go to the 790 series get the 790fx board.

    Anybody know the performance factor of the x4 slot?

    ATi cards dont lose that much performance at lower bandwidths. 8x only loses a few percent and 4x loses about 15-30%.

    The x4 slot shouldn't give a noticeable performance hit, a measurable one certainly, but nothing actually noticeable.

    For a 3870, it won't be a waste. For a 4870, it will.
