If you aren't afraid of used, I would look at msi and evga video cards. You can save a lot of money and still have warranty. Sure they probably were mined on 24/7 but just verify the fans are ok. Used 1080 could be had for around 300-400 used 1070 for around 225-300 and used 1060 and 580 for around 150-180. I just picked up a 580 8gb from msi for 160 for ebay off auction. Key is making sure the item has warranties that can transfer.
