I just installed a second 5850 today for crossfire. Power is fine, connected the two cards with two crossfire cables. On reboot, CCC seemed to detect the second card fine, asked me to enable, which I did.
I fired up the Far Cry 2 benchmark, and after a run through, discovered I'm actually getting worse performance than I did with a single card. 0_o
Not sure what is going on, because in most benchmarks I saw, Far Cry 2 was one case where crossfire scaled very well. Any clues on what could be going on? If you need any more details, I'll be happy to provide them.
Also, not sure if it helps, but here are the two cards:
SAPPHIRE 100282SR Radeon HD 5850 1GB 256-bit GDDR5...
SAPPHIRE 100282-3SR Radeon HD 5850 (Cypress Pro) 1...
