cjrgreen: Even at low settings, double-check to be sure you have the expensive eye candy turned off (SSAO and Ubersampling are the most costly). If you have recent nVidia drivers, uninstall the 3DVision crap.
Your CPU may be the bottleneck. Even though it's a Core 2 Duo, it's a weak one. And 2GB memory may not be enough on any OS. Any chance of upgrading either?
I can play at High without SSAO on an 8800 GTS 512, which is just a step up from your card, so the graphics card should not be limiting.
QueenCercil: As far as I know 3D Vision is not installed on my system. The install/unnistall only shows the drivers, PhysX and nView. Your CPU may be the bottleneck. Even though it's a Core 2 Duo, it's a weak one. And 2GB memory may not be enough on any OS. Any chance of upgrading either?

By the way, I tried running the game with High settings (SSAO disabled) and guess what? I get the same framerate as with everything disabled (1366x768). The only difference is that I have some little stutterings here and there.
I forgot to say I'm running the game on x86 XP SP3.
I'm going to see what happens if I downclock to where I'm equal to your CPU.
Followup: Yeah, framerate (especially minimums) can be bottlenecked by a slow CPU, even on low settings. I lost 6 fps by dropping from 3.33 GHz to 1.9 GHz. That's twice the hit I take going from Low to Medium on an under-spec HD 5670 GPU.
I'd look to upgrading your CPU and RAM, if it's possible in your rig.
