Issue

Using card from 10 months without problem, always with stix and manual parameter for the fan (and only the fan), 100 % speed at 50°.
Never went above 60°.

For no reason, have a big graphic glitch while playing Rust after 100+ hours without problem.

Since this moment, I have Artifact and crazy lag on Asus GPU Tweak, Google Chrome. I can launch DX9 bug with artifacts, lag and inconsistant framerate.
I can not launch any game with DX 11 or even use Chrome (Nvidia windows kernel mode driver xxx stopped responding and was recovered successfully + game crash).
The displayed GPU Speed in GPU Tweak II seems bugged (shows 119%, even if GPU-Z shows normal usage).

I tried everything posted online before formating (10+ hours trying to debug, reinstall old drivers, new drivers, DirectX, lot of library, etc...).
I formated, reinstalled every needed drivers and still have the same problem.
Did Windows Memory Check: no problem.

Here my experience with Google Chrome / Forum browsing:

I could add screenshots for DX9 / DX11 games but you get the point.

I will post and try anything asked by any of you in 24h max. I really want it to work.

I ordered the card in USA at Amazon.com on August 25, 2015. I live in France. Too bad, I do not even know if I can use US/French RMA on this product.
If you know anything that can help me, from hardware / drivers / or just RMA, I would love your advice.

Thank you very much.

+1 on replacing for the newer ones, 1070 will give you roughly the same performance for less power, 1080 will give you an extra ~20%. I would go a step further and wait for the Ti version if thats an option for you.

Took the 1080, very very awesome. Won't ever buy any Asus product. Worst Customer care ever.

Ty for your positive input.
