Great, so either the RX 480 or the GTX 1060 would be a great choice for TANE. One of the things I like is to crank up the settings with the shadows and antialiasing so I could see the more VRAM of the RX 480 helping out with all of the textures and shadows. I think the rest of my specs would go great with either card. Below are my current specs and GPU. In 2 years or so, I also plan on upgrading my motherboard to an AM4 socket mobo to allow for me to choose a ZEN CPU and one with two pci-e x16 slots.
