I hope this is the correct place for my question

Currently I use AMD Ryzen 7 5800X. Is the AMD Ryzen 9 7950X3D a noticeably better option or should I wait until 2024?
Are more cores better when exporting projects as a wav file?
If I understand this correct:

I can use more cores, If I don't use send-effect-channels - does this mean, I also shouldn't use bus-channels?
Cheers!
