The RX 480 8 GB did have a big price advantage over the 1060. For the slight gain in performance the 1060 wouldn't have been worth the extra cash, IMO. Unfortunately, RX 480 8 GB prices have jumped high enough to negate that advantage. The 4 GB cards run the memory a little slower (1750 MHz vs. 2000 MHz) and are overall benching behind the 8 GB cards. Again, the difference upon release made the 4 GB cards a non issue, but now your point is valid. The 480s do best with DX 12 but still only show a clear advantage in some titles and not in all resolutions across those titles. The 4 GB cards even less so. The 4 GB cards are a much better value now, though. 8 GB 480 vs. 1060 http://www.anandtech.com/bench/product/1748?vs=1771 4 GB 480 vs. 1060 http://www.anandtech.com/bench/product/1749?vs=1771
So with the OP's stated budget cap of $375 I really don't see any alternative to the 1060 except a refurbished 980. And the places the 980 shows any advantage may well be fixed by driver improvements for the 1060. At least that's my take on the OP's situation, for what it's worth. Oh, and Hi, Mark!
I agree that he better off buying a 1060 cause his budget allows it, But 8GB of VRAM on the RX480 is useless, 5GB would be enough for that card.
OP should remember he cant SLI the 1060 (He can only if the game allows it and its not called SLI) and if he wants to get more power in the future he must buy a new card.
