The TechReport crew has word that a future release of NVIDIA's forceware will be multi-threaded. All the better to take advantage of the emerging dual-core chips, I guess....

"Most imminent on the horizon right now is ForceWare release 75, which will bring a number of improvements for SLI performance and 64-bit Windows, among other things, but release 75 will not be multithreaded. The next major iteration of the driver, release 80, is slated to bring support for multiple threads."
