What do you mean by best? like the highest clocks ever recorded?

HWBot shows the average overclock for air cooling to be 969 core and under water that goes up too 1025.

No not highest, just as in what's a good stable overclock to overclock. Something that would increase performance to the max but not be unstable? Just want to know what others have done and run at.

And you're asking this in the nvidia forum because ... ?

If it doesn't have voltage control (and most of the Sapphire's don't) it'll probably do somewhere between 780 and 850MHz on stock voltage.

I've seen 900 thrown around a good bit. That might be a good core clock to aim for. Personally I couldn't do much with my old 5850, but that was due to XFX's poor design. You should be able to get some good speeds out of a Sapphire card.

However, make sure that you test your clocks in increments. Raise core clock 5-10 MHz at a time and run a benchmark (I like Unigine Heaven) to make sure it's stable. All cards aren't created the same, even by the same manufacturer, so asking for a "stable overclock" isn't actually going to yield you much. Your card is going to differ from others, and you'll reach your own max stable clock by testing it out.
