[Success] Asus ROG Maximus Hero XI Z390 + i9-9900K + GTX 1070

Got the RX580, I have another question now. Since I have HS 10.13.6 running with NVIDIA 1660 Ti now. Would you suggest installing RX580 and then re-installing Catalina over it or Just installing RX580, updating GPU kexts to reflect AMD and then updating to Catalina? Would a clean install be better compared to doing all the updates?
