I´d say you formulated the question in the worst way to get an accurate answer.
1070 is always going to be better choice if you have the money to pay for it.
480 is the choice for those who don't have more than 250 dollars to renew their graphics solution in case they weren't be able to run VR or certain new titles.
I´d place 970 as the real doubt at the moment to buy a 480.
