Bender help needed to improve GTX980TI and TitanX rendering

Hi all,

We’re trying to help the dev crew improving Gpu perf on these latest high end card wich have ununderstandable low performances with cycles.
The dev crew is also looking for anybody that own one if these card and have some developement skills. They don’t have a card in hand to test so any help will be usefull.

If some of you meet performance trouble with GPU TITAN X or GTX980ti, please let us know on https://developer.blender.org/T45093

Thank you all
