A new NVIDIA ForceWare driver appeared on the web which is being served on-line by one of NVIDIA's partners. This driver set is commonly distributed and it is receiving pretty good feedback.
Bare in mind this to be considered a beta driver, use it at your own risk.
There are several discussion open on these drivers in the Guru3D NVIDIA driver forums, check them here. Pretty much any geForce graphics card build in the last 3 years is supported.
