Okay so a few months ago I got a new 15” M3 with 16/512. I use it for video editing, live-streaming, productivity, and casual gaming. It runs beautifully but now I’m looking at an M4 15” with 24/512. Is it really worth upgrading? If I did this, it would be the last machine I get for years to come. But, I know this M3 of mine can handle everything for years to come.
