    I'm running the 257 beta drivers on Windows 7 64-bit. Every second or third sample the following sensors fail to gather data: GPU Temp, PCB Temp, and Fan Speed.

    The Bus Interface will drop from 2.0 to unspecified (1.0?), and back, randomly while GPU-Z is running.

    If the Sensors tab is visible, then occasionally my mouse hitches every second. This did not happen with the older drivers.

    the PCI-E speed dropping may be related to the card entering a power saving state.

    the rest, i leave to w1zzard to answer.
