After more testing it seems that valley is the only program with issues (white artifacts) for me at least, fire strike and heaven ran with no problems.

There working OK for me so far, but all my Benchmarks are 6% to 8% lower.
For my 3 Titans 9.18.13.3221 was the best driver.

Let me guess, you deleted them because you thought the newer drivers would be better??

My benchmarks are same as before, my new personal GPU score record on default clock 13.308
I hope soon drivers will be approved to save.

NVIDIA say white flashing in Valley is known bug.
 
 
 
 

Any idea of when the 780 6gb will start receiving driver updates through GeForce Experience? 

I validate result successful with new driver WHQL.
In my MODS RIGS you can see one of best GTX780Ti out of box results on market.
Same is with other KP owners, mostly Titan Black owners with overclocked cards on
1080-1100MHz base 1200-1250MHz boost clock are close to our out of box results.

These seem to be more stable than 332.21 on 680 4gb

This is the first driver that has given me a significant FPS boost in Guild Wars 2.  On maps that used to yield 40 FPS with all graphics setting maxed, I'm now seeing 50 or greater...the increase is consistent across all maps that I've tried so far.  This is with a single 2GB 660SC at 1680x1050.  My suspicion is it is because of this from the nVidia driver description:  "Introduces key DirectX optimizations which result in reduced game-loading times and significant performance increases across a wide variety of games compared with the previous 335.23 WHQL. Significant CPU overhead reductions in the driver result in performance gains that will often favor CPU-bottlenecked situations. Per usual, results will vary depending on your GPU, system configuration, and game settings."  GW2 has had CPU bottleneck issues ever since release and this may be helping.

That's 332.21 driver, third WHQL after GTX780Ti show up.

After installing these drivers on an evga 760GTX 4gb SLI setup, Battlefield 4 would consistently crash after about 20 minutes, with a Direct X "device hung" error.   I couldn't complete one match.  I reverted back to 337.50 and it's working fine again.  

Everything Ok so far! 
it seems we have a winner!
 
great drivers!!

Got flickering issues with Valley but not in Heaven.

That's a known issue running Valley with this latest driver and maybe even the last beta driver.  I see white flickering (artifacts) in Valley and not anything else as well.

I wen't back to 337.50 drivers, I had too many driver resets on 337.88 with my GTX 770
 
Oddly enough though I didn't have any problems with Valley on 377.88 like others mentioned but I did on Heaven 4.0 with them
 
so in my opinion Heaven is a better benchmark for testing stability of drivers.

These drivers are as good as the last set, but do not install the GFE 2.1, it causes some pretty serious GPU usage drops. I went from 144 FPS locked in Titanfall to 90... Re-installed these drivers with the GFE that comes with it and everything was back to normal. 

I wonder if that is what's causing my card to down clock during times it should be at full boost during gaming, I will have to uninstall GFE 2.1 and see if that fixes the issue.

what temp does your card hit? I had to raise the temp target to 85c (default is 79c) in precision so my GTX 770 didn't lose the boost clock. It's how I fixed mine

Temps are not an issue.
 
The only game I am having problems with is World of Warcraft, all others are running great on this new driver. What is happening is the card will down clock below the factory base clock when it should be at its highest boost and it will stay at full boost in the lowest graphic parts of the game. A good way to describe it is when sitting in the open world the card will be at 1215MHz and as soon as I engage a boss (world boss or in raid) it will drop to 1019MHz, some times the whole fight other times for a few seconds, if I turn my character around looking a way from the boss it will readjust back to 1215MHz. I have done a ton of fresh installs of this driver and past drivers, along with re installed the game, different in game settings, stock and OC card, bios with boost disabled, and now with no GFE. I can fix the issue by enabling K boost, but by doing so it will freeze up and give me a BSOD.
 
It is a very odd issue being that it does not take much to run wow and it is more CPU dependent then GPU.
 
Other then this problem this driver works great with all other games and bench marks.

Have loaded these drivers & tested on the games that I play.
 
All is flawless......used these on both my EVGA GTX 670 FTW & EVGA GTX TITAN vid cards.
 
I call them a winner as well.
