Probably stupid question but want advice

I've got a 2060 gpu in my desktop and I want to upgrade to atleast a 3060. I've been using pc partpicker to check compatibility. Is there anything else I need to check before I buy a new card? Like I've got a Asus B560-plus motherboard and it seems that the 3060 card is compatible. Anybody got advice on any other sites or software to check so I don't fuck it up? I've replaced most things on my pc except gpu and motherboard.
