Im finding the cpu bottleneck to be completely irrelevant. CPU struggles with heavy particle rendering, like dust and snow. At certain points with lots of particles the gpu usage can drop to 80 or so, but most of the time the card is holding 95-98% across the cards. I am holding 70fps most of the time across 3x 1080p screens, running on ultra with MSAA off, motion blur off and ambient occlusion off, cards are running at stock 6970 speeds. A big part of it though is that i run out of memory, and must use a large page file for the game to play without crashing. I have sitting next to me another 8GB of RAM that will go in tomorrow, and i will see what difference it makes. Will also try pay more attention to FPS and usage to get a better idea on averages.
