A new driver from NVIDIA was just released, it's as beta though. The drivers have some very cool new options for PhysX, and multi-monitor GPU gaming. Obviously this driver has new Far Cry 2 optimizations harboured in them as well. Also this driver includes the PhysX 8.10.13 System Software.

Beta driver for GeForce 200-series, 9-series, and 8800-series desktop GPUs.
