I need someone more well-versed in building and evaluating PCs than I to give me a simple answer regarding diminishing returns.

I want to build a PC (this will be my ninth build) that will last me for quite a while.

I run Reason, Live, NI Komplete, Arturia's V Collection, and the Spectrasonics stuff. Apart from 3rd party Kontakt libraries, that's all the software I intend to run on this machine. I can't air gap it because of the need for authorizations.

So which processor would be overkill for this application? And how much RAM can you have before it's no point in getting more?

I'm basically looking for the maximum without going overboard or being a waste.

Presently, I run an i7 with 32gb RAM.

"For instance" is not proof.
