NVIDIA has released a new set of ForceWare drivers that work with the complete family of GeForce boards (Win2k/XP only). Although this is a beta release, it should be relatively safe to give them a try since they are coming from NVIDIA themselves. The new set is dated October 19th.
* Updated driver to WHQL Certified driver for GeForce 6 series only
* Adds support for GeForce 6600 series GPUs (products supported)
* Added support for using HDTV over DVI connectors
* Added support for advanced DVI timing on all GeForce 6 series GPUs
