IMO buying a mobo now for the Zen3 is not the best idea.
1. Still no real idea of how they new cpus will perform.
2. What is a good board for current gen cpus, might not be for the new gen.
3. if only certain cpus are released on the 20th, you may not be able to get what you want.
4. who knows what the pricing is likely to be, amd might price them higher if they think they have the best.
5. who knows who and when (or even if) will release a bios update on their mobos for the new cpus.
Take a step back and wait to see what real world experiences with actual performance and temperatures are discovered
