Looking to get an ASUS ROG motherboard for a Ryzen 9 5950X but there are a few on ASUS's website, which one is the best?

How much ram do you have and at what frequency are they advertised to work?
List full pc specs innitially.
What do you need a 5950X for?
Is this a planned build or you just need a new system?
