Overclocking

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.

Temperatures

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.

Great review Tom. The 7950 is looking like a really good buy. Hopefully it drops at the £350 mark.Quote

Might be a stupid question. Were those test results taken with the card OC'd to 1150 or at the stock OC of 900mhz?Quote

I take it you've tested using the lastest Catalyst, 8.921.2 RC11? Other review I read showed recent drivers improved performance anywhere from 10-22% depending on the game.Quote
