Surely all they all do is set a number? The thing stopping me from going much higher (I've benched at 725MHz but wouldn't want to run that normally) is temperature again, the stock cooler used to keep it ok up to 685MHz, the Accelero up to 700MHz, maybe a few MHz higher but it's not really worth quibbling over that.
If you're talking about the artifact scanning of ATiTool, yeah, I use that, but I don't use it for overclocking because I like to avoid tools you have to install, I prefer setting clock speeds in the BIOS and not needing any other software running to set it every time.
We're also talking an 8800 Ultra vs a GTS here.
