Since I've decided that I stay with my 120hz-FullHD-monitor at least the next 2 years, I've chosen a GTX1070 instead of a GTX1080.
I chose the "EVGA GeForce GTX 1070 SC Gaming" with 3 years warranty... for another 20 bucks I can extend the warranty to 5 years. It is super silent in desktop mode or less demanding games and also very silent in demanding games. With less than 27 cm length it still fits in my PC case... many 1070 and 1080 cards are too long for that case.
It's a great boost compared to my GTX970, now I can play many games with 100+ fps (or 50+ fps for stereoscopic 3D) or crank up the settings from high/very high to ultra/hyper in games where fps aren't that important.
My GTX970 would probably have sufficed until the arrival of the first Volta cards, but my brother's PC needed an upgrade from an old GTX650 Ti (1 GB), so I gifted him the 970.
