i forgot to says, i'm playing in surround with 3x 24 inch (16/10) screen, thats cause the crash. I never had this probleme with my old 670 gtx. I have a wattmeter plug, and i can check power usage, but most of the time in don't exceed 750 Watt that is the very maximum, i'm around 500/550 with FF14, but a friend sayed thats its could be irregular voltage peek that could be the problem.

By the way, i still have those strange freeze problem, like everyone .
