even with relatively little GPU load , and this be on standard clock speed , the card would just shut off and I would be force to hard power off my computer . I try troubleshoot it , search forum for solution , but I find virtually nothing except a general consensus that I be send a dud card . I return it and buy a different card . I have hear good thing about Sapphire , and they be suppose to have one of the better 7850 card design , but once you send I a bad product , I do not really jump at the chance for you to send I another possibly bad one .
