I have an ASUS Strix 1080 8GB, and I love it. The Aura (RGB) is pretty good, except the bottom lights aren't that bright, top lights are though.
Aesthetics aside, I always stay under 66C at full load and around 29C at idle, even while running a 144Hz monitor. The fans turn off if the card is under 50C, and even under full load the fans only go up to about 45% and there's virtually no sound.
It's the coolest (literally) card, and most silent that I've ever had. I would imagine the 1070 is just as amazing.
