I recorded a video of it, I uploaded it as 720p/1080p should be able to see.
Happens in Uniengine Heaven Benchmark
3Dmark06
OpenGL games
Some games are more prevalent than others but this occurs a lot for me and scares me, I really would like to think it's a driver issue but 301.42 and 304.79 drivers both do this.
There is no performance issue that I know of, seems to be running up to standard with the other GTX 670's.
It happens on stock clock and won't even bother testing an underclock since it's factory clocked to 1009 MHz and lowering it ruins the whole buying the FTW Edition.
