Upping powerplay to 12% or 20% is useless. Only in furmark (and not in any other bechmark) you will get a higher score with a higher powerplay setting.
Well the fan profile is because the card runs a bit warmer than my old faithful 5850. It's really just to make sure everything is the way I want it, as opposed to there being a problem.
Thanks for giving me an idea of what to expect as I move up the freq ladder.
Do you think the VRMs would be comfortable handling higher voltages long term?
I generally had/have 900MHz as the speed I don't feel a need to push beyond, so you're right that I won't go farther, so if 880MHz is a breeze, I'll aim for 900MHz at most.
The PowerPlay I was referring to is how the card downclocks when idle, not the +20%, -20% power throttling. I don't see myself adjusting the throttling unless really necessary.
As for benchmarks... if it passes Heaven, I'm happy, no need to push the card too hard, after all, I'm going to use it for gaming, encoding, decoding, etc, not critical or life-dependent tasks that would require me to test reliability on a unrealistic level.
