Well, your CH6 has the same ROM (16MB) as the taichi x370. No news here.
MSI gave the titanium 1.0.0.3 on the first of July. Its running 4000MHz RAM. I doubt you can say that of the CH6 or even CH7 right now. Not sure of the support perspective. Asrock Taichi got it on the 3rd of July.
Why suggest the OP to go for overpriced x570 with a stop-gap meaningless PCI-e rev? I mean no disrespect but that is not money well spent.
Next CPU release could be on a new socket. But then you never know. I expect a revision on AM4... but you never know. I'm thinking AM4+.
Buildzoid talking about less heat efficient mosfets.. on by far the best x370 heatsink...

THIS. It lends perspective that you may be producing 4W/100A load more than more efficient temps, but when offset by cooling (which the titanium actually has a solid finned heatsink with heatpipes for), you may even end up with better temps.
With Ryzen 1-3, max transient current requirement is 140A. The titanium does ~260A. The Taichi does >400A. These are sustained ratings at 125*C. There are levels to overkill. Yes, at the time of launch, the titanium was pitted against the CH6 and the latter had more expensive VRMs, so buildzoid had every right to say MSI could have risen to the level of the competition. Want to see him take a dump on good VRMs with bad heatsinks? lookup x470 prime or x470 strix-I... one of the two... BAD bad bad... despite sharing most components with the CH7, the board just had a BAD heatsink. That broke it. While the x370 titanium was a 'could have been better theoretically' , it became the 'asus is downright not one he could recommend at all.'
