EDIT-Damn, I still crashed while checking out Crysis 2 on max. Wasn't paying attention to the temperatures this time...
I just got the card (superclocked version) today and started a few games. BF3, Saints row the third, shogun 2 and they all crashed to desktop (with a black screen) 5-10 minutes into the games(amazing crash considering it sounded like a movie's Transformer shouting).
The temps were all at 78 c right on the crash.
Got the precision X tool and started a stress test, I kept an eye on the temperature and it remained at about 60-68. I noticed the fan percentage speed keeping up with the temps at 1:1 ratio most of the time. Fired a game and played a full round of BF3, while still looking at temps, which remained stable at 60c.
Closed precision x and went to Shogun 2, a few minutes in, crashed again. 78 c again. Just tried it with Precision x and had no problems at all.
I can't say 100% sure as I wasn't looking , but when it crashed the fan must have not be keeping up with the temperatures. I don't remember the fan working as hard as it is at the moment when it went down, but maybe I wasn't paying attention.
Of course, not going to say that having Precision X is necessary for everyone, this is what I experienced, it could be completely different for others.
