Great card but failed on me 09/24/2013
- Relatively quiet cooler
- Extremely well-built and well-engineered w/back plate
- Neat activity LEDs behind each GPU
- Crossfire on a stick
- A litttle bit too large vertically
- Fans can get loud under heavy load for longer period of time
- Failed after a few weeks
I used the card for a few days, as I didn't open and utilize it as soon as I got it. Played some games and the card performs as advertised. Borderlands 2 even with PhysX on low is returning me over 90fps on my high resolution 27" monitor, and other games I've tried worked great. I gave it a light overclock through Catalyst Control Center and everything was good. After a few days of use the card now exhibits a problem, where upon log-in to Windows 7, the display is corrupted with rainbow gradients. The card's GPUs never exceeded the low 70 celsius temperature during the whole time, so cooling isn't an issue. After trying it on three different motherboards with Catalyst drivers 13.8 beta, 13.8 WHQL, and 13.10 Beta it looks like the second GPU is toast. I can get the card working properly if I am lucky enough to get into the O/S and disable Crossfire, but that gives me a lot less performance. Unfortunately I am one day past my Newegg RMA period, as it is for invoice date, so I have to rely on Powercolor/TUL. I hope their service is as good as others have stated. This is disappointing because the "new" 7990 reference edition is unusable due to intensely loud coil whine, and this is a far nicer card in every way. The heat sink is a rugged metal, not plastic like that other edition.
