All you nVidia card owners should know that the latest version of nVidia's Forceware drivers (beta) have been released. The 81.84 release was made available for download
from nVidia's nzone site as well as their various mirrors. As with all beta builds of a driver package you can't expect a lot of phone support for them but that's what we're here for. There are 64-bit drivers of the same build available as well, and the improvement list includes performance enhancement for dual-core processors and mixed vendor support for SLI.
