Uprading from R9 390 8GB with 250€, which card to get?

[coconut4808]

Hi, i'm gonna sell my MSI R9 390 8GB to a friend of mine for 250€, and i dont know which card to get (i'm between the MSI RX 480 4GB and some GTX 1060 6GB, but wanna know more options).
Im willing to spend up to 280€ (more or less), and the card should preferably come from the site "www.pccomponentes.com" since they have great service, 2-day shipping time and low prices (here the RX 480 4GB costs 267€).
Also, would the upgrade from the R9 390 to the RX 480 be worth it?
Which card would let me overclock it more?
Will it give me bottleneck?
Also here are my full specs:
i5-4690k @ 3,5GHz
MSI R9 390 8GB
Gigabyte GA-B85M-DS3H-A
2x4 Kingston HyperX Fury RAM
EVGA Supernova G1 750W
Cooler Master Seidon 120V
NZXT S340
I bought this PC at the end of January this year.
Any help is appreciated

Your R9 390 is pretty much as fast or faster than both the RX 480 and the GTX 1060.

You will notice an increase of MAYBE 2% going to a GTX 1060. Not nearly worth the money!

I sort of expected that, but i wanna sell the card to my friend since it's the best deal he found and for me its always nice to get a brand new component, also because black friday is near on that site and im gonna get some money for christmas so the upgrade will be like free.
Also i had some minor problems with my setup like not getting the FPS i should have in some games, etc. And i hope getting a new card would probably solve that.
Thanks for the info
