chipset, price, IO, and PCIe 4.0 x570 generally offer improved power delivery modules, though this isn't true for every model
The issue with x570 most bothers me is the presence of fans on the motherboard. Replacing them often proves tricky. Fans are mechanical parts that eventually fail. This happens because the PCIe 4.0 chip demands a lot of power from the board. Back in the day, similar problems arose with north and south bridges; premium boards used large tower heat sinks instead of fans to manage heat. So far, I haven’t seen any of those solutions. There are some models with heat pipes connecting to radiators and custom watercooling, but both come with a high price tag.
B450 doesn't support SLI or crossfire configurations. The X570 and X470 models typically offer more powerful VRMs, while most X570 units provide greater performance than CPUs ever require. Boards on these systems often lack features found in B450, such as PCIe Gen 3; X570 supports PCIe Gen 4, making it ideal for extremely fast storage solutions. B450 remains the standard choice for everyday use, whereas the X570 is mainly an enthusiast upgrade. Personally, I believe you don't need an X570 chipset unless you're specifically targeting advanced performance needs.
I align with the two individuals mentioned earlier. Typically, you should allocate about half the cost of your CPU to your motherboard. For example, with a R5 3600, aim for a solid 100-120$ board (B450). If you have a 3700X, target a decent 150-180$ board (X470/X570). For a 3900X, look for a good 200-250$ board (X570). A 3950X works well with a great 300-350$ board (X570). Higher-end boards usually offer: improved VRMs, more RGB options, metal-plated connectors on less important parts like DRAM and 24-pins, additional RGB, more SATA/M.2/USB ports, and better networking capabilities.
When using PCIe Gen 3, the system will operate at that speed regardless of your board being PCIe Gen 4.
