If you run in a window, or crossfire w/ 2 monitors, leave the catalyst control center open and watch your GPU usage? Running in a window not only is crossfire not available but the game offloads nearly all the graphics work on the CPU instead of pushing the GPU, this is a fault between the game and driver for AMD cards.
In full screen you should on the other hand see your card hitting 100% pretty much full time.

Basically AMD gfx support is straight busted, but leaving the games settings off for: Anti Aliasing, Ambient Occlusion, Depth of Field, and one that I'm not thinking of atm, and override them in CCC it'll get more of the work back onto your GPU and off your CPU, Depth of Field is Anisotropy, use CCC's Texture Filtering instead of the games as the game uses the CPU to do it's AA calcs. All of this is only for windowed mode.

In fullscreen alot of these same settings help by allowing the card to do it fulltime, and always use AMD optimizations where it can. Leaving it all application controlled leaves to many non-optimized CPU heavy calcs.

If you happen to want to risk a third pt app that does a little more, and digs deeper: http://www.radeonpro.info

It's also the fail point on the benchmark, it runs in a window and can't utilize your gfx card to it's fullest.
