Frame-rate Issues

[SuperToast]

Just out of curiosity, could anyone here that plays RnR and continually gets over 30 fps on max settings post their PC specs here please? I'm thinking about upgrading, although going off to college in a year might not be worth it.

I get FPS in the 20s and then teens when it comes to driving through the Bay Bridge area in San Francisco.

My Spec's are
-Intel Core 2 Quad Q6600 @2.4gHz
-6GB RAM
-NVidia GeForce 9800 GTX+ 512mb GDDR3 memory
-Windows 7 Home Premium, 64-bit OS

Thanks!
