1-2) PBO can push above normal boost, but you need 2600X (or other "x" CPU):

Precision Boost Overdrive essentially combines the Precision Boost 2.0 and Extended Frequency Range 2.0 to deliver elevated performance as and when needed. You will need a Ryzen 'X' processor and a 400-series motherboard to leverage it. While the AMD B350 chipsets do auto-overclock 'X' CPUs to an extent, the B450 chipset's AMD PBO ability allows for much better performance gains when using a Ryzen 'X' processor.

3) I am not sure, but i have read many people saying that if you get an "X" version, it's better to just let it do its thing, between PBO and XFR. Hardcore overclockers might think otherwise.

4) From what i read, as soon as you change multi and voltage, all boards get with stuck frequency. Workarounds i 've seen: Overclocking through P-States (ASUS Zenstates users claim success) or overclocking through offset and using "weird" multi in Gigabyte boards.For example, instead of 3.8, make it so it does 3.75 with offset. Then it keeps the power savings with the lower power states. I have no idea if this works on MSI too.

Hopefully some more experienced user will give you better answers.
Thanks! I was going crazy about PBO on non-X versions...
By the way, MSI has a problem with overclocking by multiplier and then Cool and quiet, simply it doesnt works. Another user from 2700X thread reported that it works on an Asus Motherboard, and on the Gigabyte x470 Aorus Ultra gmaing that i had before, it also worked.
