Okay, but why an RX 570? The prices on Amazon are similar enough. Also, it sounds lame, but the most I play is Modded Minecraft Java. And on integrated graphics, it's just barely playable.
My friend bought an RX 570 recently and it's much better than his previous, ancient card, but doesn't fare as well as he likes due to AMD's poorer OpenGL support. I think that's the way he explained it. For me, anything under $200 is acceptable. But under $150 would be better.
(I do plan on doing some Blender and/or Unity work also. I've dabbled in the past, but want to try it some more. Sorry, I should've mentioned that earlier.)
