FWIW, I've stuck with the reference drivers; aside from the InControl Tools, I can't see any advantages to the Diamond-specific driver, and the nVidia stuff is reliably uninstallable (I have had all kinds of problems replacing a Viper with a different card that required lots of Registry surfing to correct.) No such problems with the nVidia driver, and better OpenGL peformance, at least compared to the Diamond driver released last November.
