PR FPS Issues

Hi

I've been playing PR for awhile, and have always had lag issues, but not on all maps.

Specs:
ASUS Radeon 4850
Opteron 170 (2.5ghz dualcore, about the same as a dual core +4800 i think, s939)
2gb of DDR400 RAM (pretty bad)
DFI Infinity SLI nf4

I've played the game while monitoring my CPU and GPU usage, and noticed that my GPU usage does not go above 70%, and generally only goes to 70% when i'm getting about 80fps. It is when my fps goes to 20 that the GPU usage is at 25%, this leads me to think that my CPU is bottlenecking my game (the CPU can only do so much, so my graphics card basically has nothing to do since it's stuck at 20fps, hence 25% GPU usage).

Now my question is, what graphical settings affect CPU the most (although my lag could be due to RAM)? I've lowerd dynamic shadows and lighting to medium, but still terrible FPS at times.

Current settings are:
1680x1050
Everything on HIGH, except dynamic shadows and lighting on medium, AA on x8, 100% view distance

And, is there a PR system specs list anywhere? I'd be really surprised if there wasn't... considering it's a mod which drastically affects FPS
