Well, my experience with these crashes have been that they've only occurred with FFXIV and they increased in frequency yesterday after I updated to the latest nvidia drivers, went from once every few hours or so, if at all, to within 30 min of loading the game. I've reverted to 314.22 as some others have reported more stability with and it's improved in doing that.

I will point out that my gpu is under 50C when the crashes occur, so in my case at least it isn't about an overheating issue, doubt it's hardware as everything else is still running without any issues.
