Best Nvidia Drivers for CS:S

I saw the dod thread and I was wondering about cs:s.

i tried the latest forceware ones and it kept crashing my system, so i'm with the latest official nvidia drivers.

what gives the best fps for cs:s (and bf2!)

When you say latest forceware, are you talking about the 81.26 drivers? If you are, those are still in beta, but if you have a dual core CPU you will see a performance increase from these. If you don't, which from your sig it seems you don't, then the latest official drivers should be fine.
