Ended up finally snagging a 6990 for a decent price, performance in BF3 seems to be all over the place though. The best performing drivers seemed to be 12.3 which loaded the 6990 to around 96-99% but for some reason left the 6970 hanging around the 65-75 range. Ended up trying a few driver revisions, most seemed pretty shit for trifire performance in BF3.

Tried to reinstall the 12.3 driver and am now getting a bsod "ati kmdag.sys" error during the installation process. Rolled my system back to last week and same issue, 12.3 point blank refuse to install for some reason.

Im currently using 12.2 which seems to give me around the late 40fps range in Bf3 (ultra with motion blur msaa and ssao\hbao disabled), just not sure whats causing the crash or if theres drivers with better performance for bf3 out there when teamed with a CAP.

Any ideas anyone/ :confused: ive tried bc2 crysis 2 and bf3, so far bf3 seems to get the most load on the gpu's with crysis 2 and bc2 sitting around 40% per gpu.

Using 12.2 drivers at eyefinity res of 5760x1080.
 
Just tried with the 6970 disabled, gpu loads on the 6990 shoots upto 90% gpu1 99% gpu2, just seems like when the 6970 is enabled it doesnt know how to spread the load properly. :confused:
 
Try using RadeonPro and changing around the FlipQueueSize down to 0, 1 or 2.
 
go back to 11.12

Ended up doing that and performance is where it should be, it would seem that eyefinity and trifire has been hosed for the last few driver revisions :(
