Well at 1080p and 1440p this card (both in price and performance now) places right at or around the 980.
With this price drop, at 4k the 390x is a whole 100 dollars cheaper for 10% less performance.
This card is in a very odd place (taking into consideration small form factors)
You aren't considering power draw though.
The Nano's peak draw is 175w, which is a lot less than both of the options you just named.
It is still a niche product, but it caters to a group that very much exists.
My 390X with an i5 4440 only draws ~450W under load, being at 327W instead or whatever doesn't make $150 more attractive to me.
How do you fit a 390x in a mini ITX case??
The only reason you pay the price, is because fastest (by a significant margin) mini ITX card.
Also helps to have 123w less heat to get rid of. Not so easy in a confined space.
AMD have made 3 different cards for 3 VERY different uses. If you don't need a tiny card, buy the Fury/X.
