Fantastic Card 07/11/2012
Factory overclocked card, VERY quiet under load, effective cooler. At 950 MHz, it's almost as fast as a 7970 for much less. Coming from 5850s in Crossfire, this card is spectacular, even loaded the old Crysis to see what I was missing with. It played that on 1920x1080 Very High and 4x AA beautifully (proc is I3-2120 Sandy Bridge).
Not really a con, but if you look at the pictures on Newegg, you'll notice that it has 6-pin AND 8-pin power connectors not the dual 6-pin listed or like 95% of 7950 cards (making me wonder if its based off a 7970 board). The 8-pin connector means more power and overclocking headroom for enthusiasts.
Other reviewers note instability with these cards. Interestingly enough any overclocking, even 25 MHz would cause instability and crashes. Opened Afterburner only to find that Sapphire undervolted the card (1.03 mV vs 1.093 mV for stock 7950). Once you bring the voltage to stock, 1050 MHz is easy, and if you push it to stock 7970 1GHz Edition voltage of 1.2 to 1.25 mV, I'm sure you can hit 1100+ MHz easily. Bottom line is that this is a fantastic card, stays cool and quiet, and when properly overclocked, can match or beat a GTX 680 (depending on the game) for much less. Imagine the possibilities if Crossfired!
