@Haro thank you, that's very helpful. I was simply browsing through various motherboards, and looking at various price points and trying to weigh up what was useful or not - and well, it got very complicated very quickly.
I suppose if I'm looking at pure value - i may end up going with something like the https://www.asus.com/uk/Motherboards/TUF-GAMING-X570-PLUS-WI-FI/
What initially drew me to the B550 Taichi, is (honestly) - it looks gorgeous; then reading up about it, it seemed to have a lot of positives, like its great sound, wifi, power draw etc... where I am it is currently about £100 more than the TUF Gaming x570 - which initially sounds a lot, but I don't imagine I'll be upgrading again for 5-6 years, unless my work leads me to needing something more powerful - at which point I'll be able to justify it anyway.
I record and edit using an external interface, so I suppose sound isn't a huge factor.
...but it's shiny.
