Well your bottleneck is certainly the cpu. Tom's tests showed even the 4770 was bottlenecked by the 7850 which is 2.8ghz.
However, I think your framerates should be higher than 40fps. What driver version are you using?
In the summer (now) I run my C2D at 3ghz (to stay under 60c) and I have a overclocked HD4850 and I get 92fps on some maps and 75 on others. But it never dips less than 60fps in any scene.
I run all high settings (except soften smoke edges), 4xaa and 1650x1080
