So far so good.
Installed it a few hours ago (I rolled BACK to 340.52 nearly 3 weeks ago from experiencing the same problems everyone has been reporting on, which was the last driver prior to official GTX 970 and GTX 980 launches). Tested it with full screen on YouTube and browsing a few websites that display some mathematical renders along with testing with a couple games (FFXIV ARR/Heavensward and TW3: Wild Hunt) and running 10 loops of Unigine Valley 1.0 and Unigine Heaven 4.0. No crashes.
Funny thing is, page 16 (of the Adobe file release notes, actual official page is page 12), says:

Funny how that worked out. Otherwise, my EVGA GTX 780 Ti cards are back up to 1306 MHz @ 1.1875 to 1.2125V and under 39°C (312 K) after taking a good hit (1267 MHz @ same voltage range) from using the rolled back driver (version 340.52).
Drivers should be designed and coded in such a way as to not affect overclocking ability much...but then again, we all know the WHY behind this way of thinking by Nvidia. However, I digress.
