If I could make a suggestion, try already swapping to FOSS while ok windows to make the transition to linux easier on yourself. That is what I did, and it did wonders to help me become better acclimated to Linux.

You could also see if you can run DAW on a VM in Linux or see if your software is supported with WINE. That way you could potentially just run the windows application in Linux without a VM. Most of the time, a "Silver" rating is enough, but a "Gold" rating or above is recommended.

You know what, you're right in a way. I would honestly rather spend the extra €100 and get guaranteed results, especially since I want to water-cool and get as much performance out of that bad boy. Someone else mentioned the Ryzen 9 7900X3D, but that one is almost always out of stock, and even when it isn't, it costs almost €700. Thank you for the links, though, in case I need them.
