GPU 1070 vs 980ti for video and photo?

I ended buying a 1080 ti as I found a really good deal

To be honest, the GTX 980 Ti is a tad faster than the GTX 1070 overall, but that minuscule performance advantage is more than offset by its significantly higher power consumption. Besides, the GTX 980 Ti is an older GPU that's less likely to receive further driver and software support down the road compared to the GTX 1070.

And no official announcement of the GeForce 1100 series has been made yet.

I have not tested either of those two but I do not like the GTX 900 series GPU's.  They cannot have the Memory Clock adjusted to get free extra CUDA processing power.  But did you know that nVidia is about to have a new GTX 1100 series?  Check out my test results in the link above.
