Price - The OP has stated for sake of discussion that the prices of the two cards are the same and they basically are the same, at least here in the US.
Quiet - While the reference 480 is the loudest 480, I own one and I still haven't ever heard the fan. That being said, you can get quiet 480s easily enough so it's not really advantage 1060. The 1060 may test quieter, but if you can't hear the fan it doesn't matter what the dB are at some point.
Power Consumption -Over three years the 1060 will probably save you about $15 so when it's all said and done, the prices aren't actually equal. Though there is nothing stopping your from setting up a low voltage profile for your 480 and mining away on it.
Performance - The 1060 is about 5% faster at stock.
Overclock - I checked a review of an ASUS ROG Strix 1060 OC and 480 OC and the 1060 was... 5% faster.
So it doesn't look the the 1060 is significantly better at OC than a 480
Drivers - I can't comment on drivers specifically. I actually own a 480 so I always check to see what the new drivers bring and they seem to have constant updates for games that people use as benchmarks.
VR Performance - I suppose the 1060 is faster but, frankly, I just don't care.
So that yields:
Price = even
Quiet = even
Power = $15 to the 1060
Performance = 5% to the 1060
OC = even
Drivers = even (with the caveat that AMD will likely support the 480 longer)
VRAM = 2GB to the 480 (though I have yet to see it actually matter)
VR = Don't care
Adaptive Sync = $100-300 to the 480.
If you look at benchmarks, you'll see that with a Freesync monitor you can actually game at 1440 with the 480 as almost every game will be above the Freesync floor. And if it's not, you can always bump settings down to 'High' vice 'Very High'. I don't think you could actually game with the 1060 at 1440 without almost every game being below 60 fps and you'd have constant screen tearing.
If you game at 1080/60 then it doesn't really matter which card you get.
