Honestly, I don't get the uproar. I've personally bought a B450M Mortar for a good price from Amazon to use with the R5 3600 (3900x when that is better available and priced) last week. Reasons were because I need mATX, wanted BIOS flashback and the MSI has a good VRM+heatsink combination (shoutout to Buildzoid!), enough to even run a 3950x eventually or really push the 3900x. It was very cheap for the features and I don't have issues with MSI (H87M right now, Z87 before that, although my last Gigabyte and AsRock were good, too). It was known that we would lose the A-Series support (some other motherboards lost that when introducing Ryzen 2000) and the non-GUI UEFI is pretty much a bonus im my mind, mouse support was never great in any GUI UEFI I've used. All the features are still available as far as I know, just not as pretty and limited to Ryzen CPUs, not A-Series. If you just found out about all of this now, you need to read more tech news, this have been leaked for months now. And overall MSI B450, X470 has seen pretty good Ryzen 3000 support, most motherboards I checked are on AGESA xxx3AB while other manufacturers are still on xxx1 or xxx2 and have thus worse Ryzen 3000 and memory support. In the forums I frequent at least.For the person with a bricked BIOS: I can really recommend having something like this around: www.ebay.de/itm/263572007947 . Let me save a few motherboards/controllers already, pretty easy to use with a Rasperry Pi. Also, desoldering the SPI Flash is not that big of a deal either. If you have a fine tipped soldering iron or a heatgun it works really well if you are careful. Did that to a display controller board that I bricked (one of those to convert laptop LCDs into VGA/HDMI monitors). If you have a (cheap chinese) desoldering station even easier.Will be interesting to know if we can replace the 16MB chip with a 32MB one ourselve and flash the GUI BIOS. I'm probably not going to try though, just a funny thought.
