Not sure if this was rhetorical or not, but if it isn't, none of them. The 1070 and 1080 stand in a class of their own. AMD won't have a competitive card in these class until Q1 2017 which will be about the same time that the 1080ti drops.

I honestly don't care about this, these threads always attract those who value privacy above all else and believe that every should play on their terms. Most people do not care, and as an engineer I see extreme value in providing this data. This isn't to say that there aren't dark patterns being used here(the acceptance language is hidden in the EULA), but there is a simple work around...don't use GeForce Experience. Manually download the drivers from Nvida's website. In addition to there being a complete go around, I also use G-sync for my games which is superior technology to Freesync, so there is basically no chance that I'm leaving the Nvidia ecosystem unless they did something truly harmful to me.
