This might save you guys some time when you are testing your OC'd cards for stability.
I've been doing research on the web for different GF4 Ti 4200 64mb cards and which is the best for OC/Stability/Price/Low Noise. I came across <A HREF="http://hexus.net" target="_new">http://hexus.net</A>. They have very thorough reviews regarding graphic card overclockability.
Basically to save you ALOT of time...instead of running all the 3dMark2001SE tests over and over...
Dragothic(high):great test for GPU/Core stability
Lobby: great test for Memory stability
Check for artifacts(glitches) and if you see any, take the Core/Memory down a notch.
I'm happy to help guys! I know how much of a whip it is to run 8 min test after 8 min test. Argh! And I came across this info and decided to post it. I'm glad to see it's helped at least a couple of people.
