XFX HD7770 Black Edition S Crossfire & HD7750 DD Review

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this.

Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.

The HD7750 DD is the coolest running HD7750 we have reviewed to date, peaking at 47c when gaming ! The HD7770 BE S is only a single degree cooler than the reference solution we have here, although the noise emissions (as noted on the previous page) are significantly lower.

  1. great looking cards. still a bit costly for what you get I think. Crossfire any better than it was a few years ago? nothing worked when I had two cards. (well worked the way it should have). That is why I moved to nvidia.

  2. I wasnt impressed. but I can see the merit with two of them in Crosfire.

    Have to ask. Would the people buying one of these really be able to afford two?

  3. This is why crossfire makes sense. Obviously we have the rich guys who buy two high end boards to break benchmark scores, but back in the real world. you buy one, use it for a while, save up. then get another. you have high end card power for less money with less initial outlay.

    First time ive seen a company sell a bundle, with two in it. with two free games those cards work out at £135. its not bad value considering.
