  1. I have a XFX 9800 GX2 video card.
    I was thinking of buying the 9800 on ebay wit same specs as mine.
    Is it advisable not to mix say.... XFX and EVGA brand of 9800 video card to run in SLI?

    There shouldn't be a problem with that if the cards are both based on Nvidia's reference design (the cooler doesn't count). Do you need all that performance though? The GX2 is pretty damn fast in my book already :D

    And you'll need quite a powerful power supply to run two 9800 GX2s.

    You can mix any two cards in SLI, as long as they have the exact same GPU and BIOS. Nothing else counts, not even memory size.

    One thing that has me concerned is clock/mem speeds. XFX (I have one too) has GX2s at many many speeds. Does it matter if you have a 640 vs 680 vs 700? You can't tell just by looking at them unless you pull up the exact model number and compare it on the XFX site.
