Would help if I change my card to sapphire 580 ? Pulse or nitro? Sadly they are the same as my card, so its not an upgrade. Atm I cant afford to buy a vega.
I don't think it would help if you will still be using HDMI. HDMI has given me problems whether I was on Vega 56, RX 560, or Radeon VII. I think it's just the way that macOS handles HDMI.
If changing video cards will allow you to use two DisplayPorts, then, yes, it can make a difference.
In the meantime, I suggest you try DVI instead of HDMI.
