It depends what resolution you are running. If you are running 1440p a 1060 3GB might get you to about a 6-7 on the graphics slider, with the environmental down to 4-5. I run WoW at 1440p with a 1080 and a i7 6700K, at 100fps at 10 with environmental sliders down to 6, I dip below 100fps occasionally, but if I were to downscale to 6-7 on the graphics and lower the environment to 4-5 I could push 180fps easily. With that knowledge I assume a 1060 3Gb will give you what you are looking for at 1440p.
If you are running 1080p you might be able to get by with a 1050 Ti or a 1050 at about 6 again with environmental and 6-7 on the graphics slider.
All those settings are with AA off and Render Scale at 100%, those give the biggest drop in framerate for the least gain in graphics quality.
Other than that a 6500 will do very well with any of those graphics cards, I wouldn't go lower than that.
What's your budget on this?
