New option in CCC: Crossfire section now has "diagnostics" tab which "indicates the status of your setup", but it doesnt show anything no matter what I do (enable Crossfire, disable, disconnect CF bridges etc).
Wow, that sounds just like my problem with 3870 Crossfire in Vista 64.

No performance increase in ANY games, only in 3dMark06. Crossfire enables without a problem, but I just don't get any better FPS.
