My first ether/zcash rig, which GPU to use RX470/RX480 RX570/RX580 or GTX1070

[weareourdesires]

Hey all,

Am looking to build my first rig, and would appreciate any wise words that you could share.

From what I could learn so far Gigabyte GeForce GTX 1070 8GB G1 Gaming is pretty good and it can mine both ether and zcash well, also    
Asus STRIX-RX480-8G-GAMING and Gigabyte GV-RX580GAMING-8GD look tempting.
But from what I managed to find  RX series are not doing so well on Zcash, and am worried about fallback if ether difficulty increases.
Is 1070 worth price difference on overall?

Here is what I can buy, prices are in US dollars, if you could please let me know what do you think good option would be, it would be appreciated.

why you not buy 8gb?

price between is small but 8gb is good
my choice is nitro+ card
