depends on the game.  If all you play is FPS games, 32GB is overkill.  If you play sim games like City Skylines, 32 GB is kinda bare minimum.  I remember when Skylines first came out, and I played on 8GB or RAM... the game was pretty much unplayable after about 30,000 population.  I had a city with over a million people and it would take 15 mins to load the map, and once in, if I didn't crash, I would average 3-5 fps.

BeamNG will litterally laugh at you if you try to run it with less than 32gb ram. Its playable at 16 but only with few props meddling about
