Yes YOU WANT the 7.11 Beta 3 drivers (aka hot fix).

Fixes MANY issues (Titan Quest, FSX DX10, WIC, and rFactor, GTR2) I was having with games and lets me now run Crysis (released) in Crossfire mode.
As for Crysis, I'm low 13 fps to max 23 fps in DX10 mode:
In game graphics ALL set to Ultra/High (whatever the max available)
1920 x 1080
Intel x6800 @ 3.2Ghz
ATI 2900XT 1GB Crossfire (Cat 7.11 Beta 3)
I'm actually surprise my fps is that good after comparing with other reviews based on quad core CPUs and 8800GTX Ultra.
