Out of the box the Sapphire matches the XFX with a 900MHz core speed. Overclocking is pretty spectacular, managing a whopping 1150MHz, a 350MHz increase over a stock chip.
The cooler is certainly capable of keeping the card very quiet and cool even with our hefty overclock. Naturally it's a bit warmer when under load, but still cooler than the reference design despite the 350MHz increase.
