Very good question, cdecde12. My best answer is: it depends. Usually Apple has graphics card drivers built into the OS, so it *may* work or *may not*. They haven't exactly published a list of which ones do and don't work for sure. Maybe in Bootcamp or VMware Fusion or Parallels it might work, but that's if you're setting up a virtual machine.
Out of the box---no, probablly not. I haven't heard of a Mac compatible GTX 1060/1070/1080 yet. One may come along in the future. Usually what you'd have to do is get the card flashed with a Mac compatible ROM, which requires a PC and a whole lot of knowledge, none of which I have, or you could send it to MacVidCards.com and see if they'll flash it
which probably will cost you some money. Also, check out xlr8yourmac.com for reports of compatible graphics cards

as reported by Mac users. Darn shame, too. I have a Radeon Sapphire 7950 video card which works fine, but it has 3 gigs of video ram on board and that's it. The R9 series have been reported to work okay, but I can't verify that one way or the other. If that card does *sorta* work out of the box (no guarantees), you probably won't see anything on the screen until the graphics drivers load, so should you run into problems on startup, you're basically out of luck, unless you can live with that
