Since you listed nvidia cards only I'm guessing you have your mind setup on an nvidia mining rig already. It's totally up to you.
Well from the cards you listed up there, you should stay away from the 1080s. They're not that cost efficient.
The best option would be 1070 ti cards. Specifically msi gaming cards or asus strix will do (but asus strix cards are actually a bit more expensive.)
What I actually did is a bit different. I choose to take the best of the two worlds.
Meet my small family:
The three on the left are Sapphire Rx 580 4gb cards and the three on the right are 1060 cards (msi gaming 6gb, asus 1060 dual and asus 1060 rog strix). This gives me the ability to benefit from all the coins that are mined better on any card genre.
The 580s are actually brand new and arrived two days ago. Got them for $390 each.
I'm not telling you to do the same but just advising you to take a look at AMD cards as well before ordering as you might wanna change a bit.
