With all the backlash they've received over Vista support, Nvidia has been very vocal recently about their alterations and updates to the Forceware driver package. They've today announced the upcoming release of a Vista Beta driver within the next few days, compatible with the GeForce 6, 7 and 8 series. The most notable feature of the package is SLI support for the 6 and 7 series, including the 7950 GX2.
A host of bug fixes is also promised, and a much-needed boost to OpenGL performance. If you've had the pleasure of playing several OGL titles on Vista, you probably noticed the significant degradation over the same hardware in XP. They're fixing this, and clearly want everyone to know about it. Interesting that they are now going so far as to announcing pending beta releases.
