    I've just replaced my venerable HD4890 with a MSI 280.
    So I'm now wondering if the 4890 can be xfired with the 280?
    And even if I can, is there any point ...will I see any performance gain?

    You can only crossfire two of the same card model. Those two have different architectures, wouldn't work even in the wildest of scenarios.

    IIRC that's not entirely true, CF is more flexible than that, you could crossfire say a 7950 and 7970. But yea in this case it wouldn't work.

    You can Crossfire the same Architectures does not have to be the same card but those 2 cards are from different eras.

    True, but only some cards in the same architectures work. The 7950 and 7970 are almost identical cards, so they work.

    But they do have to at least be the same architecture.

    Think a company called Lucid played with the idea of combining completely mismatched GPUs and integrated Graphics. Made it to the end consumer but didn't make much of a splash. Not surprising given any support for disparate technology with drivers would turn into a nightmare!

    Lucid tried it, as it turned out, the gains weren't worth the power consumption nor was scalability nearly as good as it could've been.

    Hi fingerbob69,

    The 280 can only be xfired with the following cards.

    7870XT/7950/7970/7990
    280/280X

    Regards,
    Matt

    No, different architectures friend.

    280x is tahiti and 285 uses the new Tonga architecture.
