I don't like the price performance, I will probably wait and see if the prices come down, I'm looking at the GTX 1070.So the question still remains: who's gonna get one?
Article from Anandtech said according to the graph the GTX 1080 is only 20-25% faster than the GTX 980ti, the 1070 7% grater performance distance gap from the 1080 compared to the GTX 980 GTX 970 series.
marketing slides put the average at around 65% faster than GTX 980 and 20-25% faster than GTX Titan X/980 Ti, which is relatively consistent for a new NVIDIA GPU http://www.anandtech.com/show/10304/nvidia-announces-the-geforce-gtx-1080-1070/2
