ESXi on bare metal: Ryzen 5 2600 or i-5 9600K - for home NAS and virtualization.

Hi,

I narrowed down my search to ryzen 5 2600 or i-5 9600K - for home NAS and virtualization.

The two resource intensive activities will be 5G oracle database maintenance and queries + Plex + Resilio Sync...everything else (mail server, web server) is very low use.

I intend to instal ESXi on bare metal (Type 1)

I have two questions A and B:

(A)

What are your thoughts on these two CPU in terms of:

1. Performance and temperature/cooling req.?
2. Ryzen 5 2600's support for virtualization; I heard AMD is less mature for virtualization compared to Intel...is that true?
3. Installation issues with ESXi and Ryzen 5 2600 (some reported purple screen of death)

I've read so any sites RE more CPU is better than faster CPU, and vice verse, that my head is spinning. The sources are incredible contradicting.

(B)

What about these mobos:

1. Intel: ASRock > Z390 Phantom Gaming-ITX/ac
2. AMD:  Specification for B450I GAMING PLUS AC | Motherboard - The world leader in motherboard design | MSI Global

I heard that many get Purple Screen of death on any motherboards with AMD components.

Thanks.
