They are from the same family, aren't they? I'm thinking it's possible.
I agree. Not the best solution for sure.Yup, I think you are correct. I just now realized this. They can be crossfired, but I think the RX 580 will limit itself in terms of shaders and memory accessible to be like an RX 570 though. Not really worth going for this setup, at least in my opinion.
