Summary: Sometimes it crashes drivers, but restores within seconds. I think that the problem is in drivers, and not in graphic card. Anyway, I don't know the way how to check this.
Pros: I upgraded from HD7750 and the difference is very huge. Now I just turn ultra settings on my favorite games and enjoy what I see on the screen., It comes with nice ASUS GPU tweak utility where you can control its perfomance.
Cons: It uses 2x6pin connectors and needs more power than 270(non X) version.
Summary: Fan duty spikes for no apparent reason according to the monitoring software, and that doesn't make sense. The GPU usage also spikes while watching youtube vidoes but stays fairly regular during gaming? These are not real problems because I cannnot audibly hear the fans speed up and GPU usage during gaming is what really matters with this breed of graphics card.
Pros: NOTE: VERY EARLY REVIEW, WILL UPDATE AS OWNERSHIP INCREASES
Cons: I have a few issues with the build quality. Yes, there is a brace to hold it all together like they mention in the review video, but that doesn't mean that the card doesn't flex under its own weight. In my opinion, that is not a good thing.
