I installed 64GB when I built my current rig five years ago, because I do (or, did) graphic design for a living and Photoshop will use all the RAM you can throw at it. I routinely worked on files in the 10GB size range, and sometimes larger. The RAM makes a big difference in how long filters take to render on such large image layers--from minutes, down to seconds.

I'm a software architect. I work with large amounts of data. And a sizeable RAM disk is generally useful for many purposes. And yes, I also run AI locally, though that's what my RTX 4090 is for.

You don't understand how many tabs I need open.
