So I found a good performance balance for my:
Opteron 165
2GB PC3200
8800GT
Settings are set to:
-Enhanced dynamic lighting (*NOT* DX10)
-Turn grass distance down a bit
-Turn shadow quality down a bit
-Everything else to default settings ("high" maybe?)
-1680x1050 resolution, no AA
Gives me FPS fluctuating between 20-60 depending on the situation, remains playable
