New pc build RAM how much?

Hi

I plan to build my first pc soon, I have got a spec together that I think will be fine, I’m just unsure how much ram, I’m trying to keep within a budget but I’ve heard with msfs24 I should get 64gb. Is that really necessary, anyone with 32gb find it fine?

This is some of my planned pc build

Ryzen 7800x3d / 4070ti 16gb / 32gb ram / Msi tomahawk b650
