It is a heavily CPU dependent game and it particularly maxes core 1, although some card settings do have a noticeable impact.
Faster cards will give you a higher overall / average frame-rate, but it still likes to plummet.
At the resolution you are using, it is definitely CPU bottlenecking.
I have a new Phenom II x4 3.4 on the way so I'm hoping that will help.
It will, but I wouldn't expect miracles
