Also a X800 crossfire version existed, just can't find it anywhere. It's core clock ran at 400MHz and I don't remember the RAM speed. If you flash the X800GTO to X850 then you should have no problems with the X850 Crossfire. But the main problem is that since it has only 1 TMDS, is limited to 1600x1200 at 60Hz max of resolution, still a good performance boost, but doesn't worth the hassle of it's issues like SLI, some games not compatibles, some settings not working the way they supposed to, random crashes, instability, higher power consumption, but the X850 crossfire the last time I saw it, it was priced over 150 bucks, is not bad for real. But if you save your money and go to the X1950 PRO you may get the same performance, a bit less or a bit more depending of the games, AVIVO, Open EX HDR and SM 3.0 which could be mandatory in the future even that it just bring some performance improvements only.
