RX 570 4GB

hello there,

I have a 1060 6GB for my windows, but I want to be able to install Catalina, so I saw some local person selling a RX 570 4GB for CAD$100. I want to connect 2 4k monitors in 1440p scaling with OSX. Will I be able to do photo editing? I won't be gaming. It's also a MSI brand, is this ok?

My current build is i5-6600, 16GB, 1TB SSD

thank you.
