Besides, a dedicated computer for music production has a low entry cost since you basically only need a decent amount of ram. My studio computer has an old i7, 32 GB ram and it doesn't even have a GPU and the price was less than $500 a few years ago. It's going to outlast my current gaming rig and probably my next one as well.
I totally get what you mean by productive setting. I achieve that with two user profiles - one for music (dark colors, only DAW and GuitarPro, no social networks or messengers), another for fun (brighter colors, steam and battlenet). It is a much cheaper - free! - than $500, and I get to save some space at home.
In the end different strokes for different folks I guess. If your setup works for you - keep it up!
