From what I've seen the 980Ti and 1070 are about even, but with the 1070 generally winning by a small margin.
Which is exactly what we would expect? It's better than last time when the 780Ti was mostly faster than the 970 at release.
A £320-400 card faster than one that costs 500+, that uses less power, has more memory and more features... seems pretty good to me.
Indeed. Shows good gains in dx12 aswell (hitman and ashes) over the 980ti
