I will be right here with you.
I picked up 5 GTX 1070 ti cards yesterday. Expected to be delivered next week.
I plan to setup the mobo, update the bios and install windows. Get that stable and then add a GPU and install drivers. Test the over lock settings until I have a profile I like, and then add a card, add drivers and add profile and then test to see stability and keep doing that with each card until its all running.
You might take a look at SimpleMiningOS over on the forums -
https://bitcointalk.org/index.php?topic=1541084.0 . For 2 bucks a month I think it's well worth it on a 5 x 1070 system.
Super easy to setup and the web interface is honestly worth a lot more then 2 dollars a month if you plan on changing coins you mine.
