Prices for the 9900k war also through the roof for the first couple of weeks because of the shortage (630€+). If you ask me, that was an even worse situation.
I guess I can say something, as I'm on that one.
Hands down, this is the best x470 board out there. But it also has some strange design decisions like just coming with Blue-tooth 4.2, both m.2 slots are sharing lanes with certain PCI-E and Sata Ports (common problem) and I was never able to make the DTS stuff work (software doesn't respond). Not a deal breaker, but worth mentioning.
VRM is excellent, memory compatibility was good for me too (3433cl14 on 2x8 and 3200cl14 on 4x8), and it's a feature rich mainboard. There is not much to not like, except for the price.
And that's why I wouldn't recommend getting one, when building a new AM4 system. The CH7 WiFi still costs ~300€ over here and you can get a nice x570 board for that. Take a look at the x570 Strix-E, in many ways it is very similar to the CH7 but just more modern. If I'd build new now, I'd get the new Strix-E.
Unless there is a good deal for the CH 7. 200€ or less? And you got an excellent MB.
