Should we take the thread back to its title guys? Ok, this set seems quite stable for my GF2ti without crashes except once in CStrike.
I also love the refresh rate fix for D3D plus the new display properties interface. As for the great performance issue, situation is quite mixed up. RTCW and quake go around 10% up or stay the same depending on the resolution I test, Max Payne shows a significant drop in both 1024 and 1280 resolutions of around 25%(!!)

while FIFA2002 becomes slightly crappy at 1280*1024... Almost forgot-3DMark falls around 150pts back too....
I could barely say that nVidia is optimising their drivers for OpenGL usage...!

In the end, a cool set for beta stuff but Santa Clara has to try more to get that 25% increase in performance it claims in the web site...

I 'd love to here more impressions though plus your benchmarks- Come on, I know u all gave it a shot...!
