Re: Is it worth it to push the 6800GT?
It can vary but normally what I have seen is 'sprites' (white specks, snowflakes, whatever) showing up when the memory is getting too hot. Artifacts such as bars running across the screen, or triangles, misrepresented color, etc. when the GPU is getting clocked too far. Also the screen locking up or freezing or getting kicked back to the desktop are indicators.
