YOU INQUIRED:
I found on Best Buy for $160, that there is a motherboard that can support my ryzen 7, wonder if it will work. www.bestbuy.com/site/msi-b550-gaming-plus-socket-am4-usb-c-gen-2-amd-atx-gaming-motherboard-pcie-gen-4-black/6424047.p?skuId=6424047
Response to subsequent inquiry
The prospective replacement motherboard you viewed and inquired about supports AM4 socket 3rd Gen AMD Ryzen™ processors.
I cannot say for certain if the cpu will or will not work because any conjecturing or investing my time to locate the answer creates potential liability.
However, you are admonished to speak directly with the manufacturer's of the products.
