Naw, you don't want a 1080. They are a in between step in nVidia's architecture, so you will definitely wish you waited for Volta when it comes out. I'll try it out on my Fury X machine to see if it was really necessary.
I'd hardly consider the fact that the 1080 beats the 980Ti by an average of 25% as an "in between step" in advancement. And regarding the Fury X, it was supposed to be a 980Ti killer and wound up being 5-10% behind it on average in most games when released in summer 2015...and that didn't include when taking into account 980Ti overclocking, because the Fury X couldn't be overclocked anymore as it was maxed out from the factory when shipped. Yeah I remember all the fanboy comments on both Tom's and Anandtech claiming that the Fury X would destroy the 980Ti. In fact, they are still out there for amusement.
Regarding Volta, I'm hoping AMD brings some real competition to Nvidia...Nvidia needs it. However, their past several high end releases have not been Nvidia destroyers which is very disappointing. AMD is well known for lasting longer in gaming over time than Nvidia, which is why I always recommend AMD over Nvidia for mid-range GPUs. But the Fury X was nothing but a $650 fail. Just a year and a half later, it's only roughly equal to a reference $380 GTX 1070 in DX12 games, and gets destroyed by it in DX11 games.
