help with first hackingtosh

Hi

i just purchased a amd ryzen 5950x with a asus b550 pus tuf motherboard and samsung nvme 980 pro and amd rx5700 (not xt) gpu

i was thinking about going with the catalina distro as my soundcard is not supported in big sur.

Could some of you guide me to what kext and ssdt´s i need for this configuration using opencore 0.6.4 which i can read seems to be the best option.

thanks in advance and sorry for the noob question
