I Recently got a ASUS TUF Gaming X670E-Plus which also has support for ddr 5 and pciex gen 5 i have 7000Mhz ram installed running at just that faster than the maximum the board is rated to support and it runs fantastic i also have the amd ryzen 7950x so might be an option for you and still compatible with your current processor.
