Default tri-crossfire?

I don't know much about crossfire but I was wondering if it would be possible to run 3 4890's in crossfire like a sli setup or only 2 4890's?

thanks for any help ;)

its possible.. benching results would be great, but gaming would be no better than just a single gpu.

You can run up to 4x 4890's in Crossfire, and contrary to element's experience, Crossfire works pretty well for me, but gains after the second card drop enough to make the third/fourth card(s) questionable. After running every type imaginable, it's not the Crossfire Technology that brings those losses, but the underlying pci-e/cpu architechture.

i wouldnt go with 3 4890's right now. 2 4890's will do just as good as tri crossfire. save your money for the 5870 series
