I got a phenom 945 3.0gig  like almost 2 years ago. IM playing battlefield 3 and i have 3 6870's and the fram rate is all over the place. I got from 90fps to 30fps and its jerky as crap and microstutter eveywhere. I shouldnt be having this problem.

My specs are

Visontek 6870x2 2gig

Sapphire 6870 1gig 

Biostar Ta99ofxe motherboard

8gig  PNY  DDR3 1333

Phenom 945 3.0gig i overclock to 3.2 but dont see much diffrence in performance.

Some games are more CPU-intensive than others.  I don't have BF3, and reports on where it fits on the scale are contradictory.

With vsync disabled (you should be using it when playing normally, though), use GPU-Z (three instances) to log GPU usage while you're playing.  You should also log CPU usage, though I don't know off hand of a utility that will write it to a file (I use two monitors).

If your GPU usage is relatively low and CPU high, then you're CPU-bound.

Just click "Log To File" in GPUz in all 3 instances
