Pros: Cool, Quiet, 2x 8 pin power
Cons: 2 year RMA
The card so far, is fantastic. Immediately popped it in my case, uninstalled my Nvidia drivers, and installed CCC + Trixx + Raptr no problem. The automated graphics config is not quite as organized or smooth as GeForce Experience, however it is controlled by the community so I think as the drivers progress and usage increases, it will be better.
Immediately threw 1000/1350 in Trixx to try it out, saw some strange "possible artifacts" in Arma2 so decided to back it down to 950/1250, this didn't get rid of them so I jumped back up to 1000/1350 and played some Crysis 3 to determine if it was GPU related. Crysis 3 ran fine, but was not able to run smooth 60fps (I'm at the end of the game, when there are huge environments and big explosions) little disappointed about that, but turning down some settings would definitely take care of it. GPU-Z showed steady 99% usage during gameplay (this was also with 6pin + 8pin power, now I am using 8pin + 8pin). Temperatures never broke 70 degrees during gameplay, and I'm sure this card can handle more. I turned up the fan profile slightly because I don't trust the "cool and quiet" thing. I'd rather put my headphone on and keep it a little cooler, however without my headphones on I hear my CPU cooler and intake fan over the card.
Overall this card has been very fun. It's replacing a GTX 660 (which I paid almost $200 for new, about a year ago ). That card is now going into a guest rig. I think this card has incredible bang for buck right now if you can find it used, if not then I would probably go with the R9 R80x.
