Just checked because it seemed off, Cyberpunk recommends 12 GB (8 GB is the minimum), so for that 16 GB is plenty.

A lot of games showed drastic improvements when I upgraded from 16 to 32. And I also game with stuff like chrome, Spotify, discord etc opened on the side.   
  
And I doubt 16gb will last you more than a year or two. People were saying 8gbs fine not too long ago.  
  
Personally I would never recommend anyone getting anything below 32 unless they’re on a budget.
