Testing Overclock Stability

[DigitalEmperor]

What can I use to test full stability on my graphics card overclocks. I have a 6800GT and come from a world where ATI Tool reliably and consistantly can find the maximum stable overclocks and does so via long streneous testing. Is there anything similar for the nvidia cards? I have a feeling the "Detect Optimial Frequencies" just doesn't do enough to ensure stability. Sitting and watching for artifactings while trying to run a game is not only very tedious but also very subjective. Artifacts can appear in places that I am not looking for and hence, will go by unnoticed by me.

If anyone can please help out in listing the steps they've taken to ensure a stable overclock I'd very much appreciate it. Thanks so much guys.

You can still use atitool to detect artifacts
