Despite the caveat of active cooling, the impressions of X570 have been almost universally excellent. The chipset performs well, is stable, and is reliable. Go figure. Not only that, but MFGs finally pulled their heads out of the sand, and most X570 boards have greatly improved VRMs as well as improved I/O options. So X570 might be better than you think... The problem with B450 is that the large majority of the boards have barely adequate VRMs that will throttle an 8 core CPU. The VRMs on B450 are such an issue that lists of known good boards are being compiled. I wouldn't even use a B450 ASUS or Gigabyte board. BOTH made some really weird mid-range X470 boards with garbage VRMs that can only really handle a 6 core. Their B450 boards are even worse. Surprisingly, MSI is at the top of the list. Their 4+3 phase boards have by far the best VRMs for B450. The MSI B450 Gaming Pro Carbon is a little pricey but is a spectacularly equipped board for the price with great cooling. Like the kind of cooling and VRMs where it's recommended for OCing 8 core CPUs. Several of the MSI B450 boards below it in the lineup, B450 Mortar and Tomahawk being the standouts, use identical VRMs however with lesser cooling. That said, even the boards with lesser cooling have a better VRM solution than everyone else's B450 boards. Considering how much better MSI's design performs in the real world, I wouldn't even look at other brands for B450. The rest just straight up aren't as good. It's not even a matter of comparison anymore. In fact, their next board up, the X470 Gaming Pro carbon, is almost literally the B450 board with even better VRMs and more I/O. It has the weakest VRMs of any PROPER X470 board(The equivalently budget-orented Gigabyte and Asus boards are a joke) and is still far more than adequate for the chips the board can take. X470 was fine in general. manufacturers learned their lesson on high end boards after X370. Nearly every single X470 board made has been solid. B450 though, they grossly underestimated the number of people who would be using 8 cores on them... X470 in general? It surprises even myself that I can't recommend Gigabyte OR Asus. If you wanna get like a $200 board then yeah it'll be awesome. Every MFG makes kickass high end boards. But for some reason a lot of manufacturers struggled with mid-range boards for the platform. So X570 is also a nice step up in that regard. You have far fewer boards with crappy power handling in general. I can wholeheartedly recommend the budget oriented x570 boards from any brand.
