I had a build using this mobo and pretty happy with it.
The problem is not the few ITX but I would say more on the lack of headroom from the Ryzen CPUs to overclock as nicely as the intel.... I have the Phantom B550 and its running great but AMD out of the box already have plenty of performance, personally on a ITX I keep things at stock as it...
Interesting round up.,.. I might just end up canceling my Extreme 4 order as I been waiting for a while now and buy the Steel Legend that is pretty much the same.
According to Buidzoid, Asus and Asrock did pretty good this time around and the Gigabyte a bit more disappointing, but obviously you have good and bad models on any brand, but for me I decided to go with the Extreme 4, solid VRM, great features and really sweet price for the specs.
Now just...
It's nonsense to buy B450's right now, there's entry level B550 for less than 80$ and very solid mid range for 115$ like the B550 Phantom which is at the same price as some B450's.
When you have boards as good as their X570 brothers but costing less...
I'm looking to buy a B550 Extreme myself! Top of the line VRMs, good features and for just 180$.
You have good options, the B550 M Steel Legend was listed just around 150$ which is a good price for that board.
The PCIe 4.0 will become more usefull once you see more storage devices taking advantage..
It seems that they are a bit pricey but they look that are far superior to the B450's. for something in betwen the B450 and X570, its a good option. I might get a B550 Extreme4.
If you are willing to wait a few more days, I would go with a B550. Personally I think you get a much better mobo for 190 compared to a X570. I'm looking at buying a B550 Extreme4 myself.
