If you like recording, you're going to be wanting to use more of everything. I mean, you're spending $3k, might as well just give into the 32 GB RAM. It's not THAT Much more expensive when you consider how big your budget is already.

Just something extra that popped into my head, if you use your CPU to encode your streams and/or recordings it may cause some lag. Some may disagree with me but even on my GTX 1050 SC, encoding recordings and streaming using my GPU through OBS works much better than my 8 GB of RAM and Intel i5. xD
