What are you doing on a 10 year old PC that would necessitate 128GB of memory on the new one? 32GB should be sufficient when it comes to ram for most users. 64GB max. Even for the next 10 years.
Edited to reflect OPs edit!
I'm sitting at around 90% utilisation constantly on 32 and FF keeps crashing because I'm out of memory.
I work in the tech field, so it's sometimes docker, lots of CAD, games (often with said cad program and browser in the background)
Edit: just realised I typoed, it's 10 years, not 20, sorry.
You may want to check if that's 90% of active utilization or things just holding onto the memory "just in case". If your running CAD, gaming, and have containers actively running at the same time, then yeah 32GB may just be cutting it, but I would find it suprising that you're actively using 90% frequently.
I guess more ram could mean not having to worry about spinning the containers up and down, but the only time I hit anywhere near 32GB is when doing heavy data workloads and those are times I'm not worried about running anything else.
I have one thing that drives my RAM usage up to about 45ish GB (64GB in my desktop) and that's Star Citizen, and the whole reason why I installed 64GB.
Outside of that though, it is nice to have the headroom to basically do whatever I want, and multitask like crazy. But I rarely see my usage get over 25GB outside of SC.
For reference, this is on my desktop running Nobara
