I have 8700K and RX580 with 18,3 SMBIOS. Is changing to 19,1 or 19,2 imac SMBIOS best? 19,2 has nearly if not same CPU and real mac has dedicated GPU? People seem to say 19,1 is best for dedicated GPU but 19,2 seems closer to my hardware. I run a headless connector for igpu/quicksync. Any advice? Thanks!
