Windows 10 is why you need 8 cores to produce music nowadays. It has nothing to do with the music software that would run fine on 1 maybe 2 fast chips.
Windows 10 is just a gigantic, "Death Star," sized OS. Seriously, I'm using 7th gen core i5 kaby lake, and the thing can handle windows 10 - but coasting through it - not blazing through it.
I've tried lesser chips with Windows 10 and omg is it a sad story
