Am I right in thinking this is a case of a cpu bottleneck? Maybe because the cpu has the physics and sound engines to handle as well as passing frames to the gpu. So far, I've been messing around trying to get sli working... but maybe it is working and I have 2 cards sitting round waiting now instead of 1.
You could try lowering the sound quality from both the settings.ini file and control panel(your X-Fi won't make a difference in this game).
