Somewhat nervous to upgrade to these. As I've been facing black screen driver resets semi-daily, on every other version of 471. Even had the desktop corruption discussed in the previous thread a single time. If the driver resets once while working with an application(2D/3D, does not matter) it'll keep doing that whenever that application is restarted and in focus, until the system is rebooted. Initially i thought it might be dying hardware, but 466.77 has been rock solid for almost 4 weeks.
