Quite card that stays cool under load. Plays most games flawlessly at 1080p on high-very high settings. The 3 games you get from the Never Settle Radeon Gold Reward Bundle are an added bonus. Crysis 3 looks amazing. (Read More)

I upgraded to this card from crossfire 6970's and benchmark were showing that this card was equal to and sometimes faster than the crossfire solution. Very impressed with this card, it'll flex anything I throw at it. (Read More)

Yes, it's voltage locked. However, I have read things saying that something in the neighborhood of 1150/1575 is still possible. But this is the internet, so take it with a grain of salt. I haven't bumped mine up that high yet, but even bumping up the core another 100MHz made ZERO impact on the core temps. At full utilization, it still doesn't break 60 degrees C, the fan speed has never gone above 63%, and the noise it makes is still barely noticeable.

All in all, I think the message here (and from other comments) is that it will OC some more out of the box, but don't expect godlike OC numbers. (Read More)
