I'm in a 👏 TREAT YO SELF 👏 mood, so I might buy the Dell XPS 15 (2020) today. I'm just not sure whether to get the 16GB or 32GB. Is it better to splurge now and get it right immediately or to go with 16GB and then upgrade parts of it in a few years?

Use case: office-y stuff, video editing 4K and Goat Simulator/Rollercoaster Tycoon.
