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.

It is just a pain in the ass to find out what network module exactly is being used in the motherboard before buying it. ASUS only says the ethernet is Realtek, and that's about it. I just hope that those one or two online probes I saw of the board on Arch that said it worked OOTB were correct.
