I replied with this message on a different topic:
"It's the card. I had a 100% stable system before installing my XFX R9 290. Ever since it's install, I have had constant BSOD/Rolling Random Restarts.
I tried everything, testing every componite I had, and even put my CPU under a stress test. They all checked out perfect condition.
I even went as far as fresh installing windows 7 and MULTIPLE driver installs. Granted, spent many hours trying to troubleshoot my problem.
Last resort, I pulled out my r9 290 and installed my old HD 6950 to see if it would return the system to normal.
All better, even with the 9.5 Beta driver!
I just RMA'd my r9 290 to newegg to see if a replacement will fix my problem. If it does not, I am going to demand a refund.
(Note: I was also experiencing below average fps for EVERYTHING with the card. Bf4, Heaven 4.0, Assassins Creed 4, etc.)"
I would recommend RMAing the card immeditally to the dealer you bought it from. I have read many people have solved their problems this way.
