Crossfire and Crossfire-X

[KyleIsABeast]

Is there a difference in crossfire and crossfire-x? I want to get this new mobo and pop in 2 4890's. The mobo is crossfire ready and the 4890's are crossfire-x ready.

Thanks!

Well, essentially crossfire-x is simply a re-branding of crossfire and alludes to using 3 and 4-way crossfire, which you technically can do with just two PCI-E 8x slots. Anyway a 790FX board with 3 or 4 slots would be what crossfire-x is alluding too, while a board with just 2 8x slots would refer to a crossfire board, though such a board would still be labeled as "crossfire-x" under the current branding.

By the way, if you're going for a low cost crossfire board I'd recommend looking at an ASRock board as opposed to one from Biostar.

If you're in the US, I would suggest shopping from newegg.com opposed to tigerdirect.com
