My board has been completely stable so far. I have managed to overclock to 3.2 ghz with no voltage changes. However, there is still the PS/2 bug which has not been fixed yet. Others with this board have reported worse problems, such as inability to boot with certain brands of ram which has never been resolved. Also, the north bridge runs ridiculously hot (>70 C) and requires the use of the noisy fan. At this point I would say steer clear of the 680i.
