The AMP! (non-extreme) is pretty close to the 1080 reference, and you aren't going to find a ton of difference between any of them unless you are trying to overclock to the extreme for those few extra FPS. Any 1080 on the market is going to blitz any AAA game and I'd just go for the best you can afford without getting one of the super expensive models because they are just overpriced and its throwing money away. Check you ahve the case to fit the card you choose, thats the most important thing. Brands like Zotac and Palit undercut the big players because they aren't as well known and might not quite have the same aesthetics or RGB LED's etc, but they are pretty much alike. I dont even find backplates make any difference to cooling myself, its just for prestige if you ask me.
