I just picked up a 4850X2 card and can't seem to find any info on the net as to if I could run two of these cards in crossfire giving me four gpu's. Anyone know if this can/has been done and what are the results?

Thanks in advance,
Nick

Yes, it's called Quad Crossfire but I ask you...In Gods name why?

I have no desire to ever do it, just curious to see if it were possible and how it would perform. I am not even a gamer and do mostly video editing/photo editing so just the 4850X2 is way overkill.

See:

Scaling for most games are not worth the extra money for a Quad fire set up. Quad SLI/QuadFire doesn't scale that well, granted QuadSLI dose a job little better than QuadFire

Yeah pretty much. The drivers are getting better, but unlike the nVidia drivers they are not threaded well to take advantage of multiple cores and they CPU overhead is significant. While crossfire performance is good for 2 GPU cores, past that it isn't so great :D.
