Based on those benchmarks in the first review, I'm not sure there would be any reason to pay the extra $50 for 1060 against 480.
Your opinion is your opinion and your money is yours, so what you say is as valid as anything.
In my case though, the 50$ are worth so much to me over an AMD card. And man, I like AMD, I mean ATI, I like these guys, they have little market share but I appreciate that they offer similar or very oh so slightly less performance, but have cheaper cards. However to me the 50$ more give me (in my view and with my money) an awesome recording software, shadow play, day 1 drivers, Ansel, streaming to a tablet, and to top that usually a little bit more performance. I like what Nvidia offers on the software side, and I even appreciate little things like the tweak/graphics guides for major titles. I just feel my 50 bucks are more than justified, specially when generally I get like a 5% or 10% increase in performance over AMD, which is not a lot, but still nice for 50 bucks.
We're all different and putting this in a TL;DR post, I'm not sure there would be any reason to not go for Nvidia.
But as I said we all have our own views and I understand you see that way. I work in retail in this space and I do suggest a lot of people get a 480. Personally though, I prefer Nvidia's higher cost vs what it offers me vs what AMD offers at a lower cost.
Edit: with this I forgot to answer your question. In mmy opinion with Nvidia, but from what I've read lately driver support has been fine on the AMD side.
