HD 7770 Black Super OC Edition D. D. Conclusion
There is no doubt that XFX put a lot of time and effort into the design of these cards. They aren’t just great looking but they perform really well. These are the most powerful cards right now in this price range. These cards represent a really amazing value for the budget minded gamer. This is the market that these cards are aimed and they really do hit the mark.
One thing that I am not all that impressed with is the way that the cooling shroud allows most of the hot air from the card to be dissipated within the case. If you don’t have a case with very good airflow, this is something to consider. To be perfectly honest though, there wasn’t all that much heat being generated from this card. It really didn’t blow that much hot air out of it at all. Using our laser thermometer we never recorded temperatures above 52 degrees Celsius on the GPU and the exhausted air was never more than 40 Celsius. That’s pretty impressive and it means that you really don’t have to worry that much about airflow. It’s always my recommendation though that you have a dedicated fan directed at your graphics cards and a decent exhaust fan for the top of your case.
You really have to hand it to AMD and XFX on the design and performance of this new card. It really will appeal to a wide range of users. It would have been nice to see at least a gig and a half of dedicated memory though. If you are planning to use this on one of the new 4K capable monitors, this memory limitation could severely impact your video performance. These monitors aren’t even available yet, but I would recommend using a card with a little more dedicated video memory for those types of displays. These cards will support them, but I have a feeling that you will notice a difference in performance between a card that only has a single gig of video memory and one with more. Your dedicated video memory is what provides your frame buffer and if you don’t have a large enough frame buffer your frame buffer will have to be offloaded to your slower system memory. This will definitely have a negative impact on your overall video performance.
These cards are really geared more for the budget minded gamer and in this respect they really do shine. These are sure to become very popular cards and with the initial release drivers that we were provided, these cards were still able to deliver very playable frame rates at high settings and resolutions. There really isn’t much to complain about if this is what you are planning to purchase these cards for. For those that are going to want better performance and frame rates, I really don’t see why these cards can’t be pushed a little further. At less than 55 degrees, at the increased clock speed that XFX already has these at, this should indicate that they can be pushed quite a bit further. I would suspect that they would also benefit from having additional cooling that would be provided by most cases. We had these cards set up on an open-air test bench. There is no question that this new card from XFX fully deserves our Editor’s Choice award, here at Motherboards.Org.
