Both Amazon and Newegg have the MSI Performance Gaming B450M motherboard for $79.99.
This B450 board would pair nicely with the recent , or better yet, if you’re not afraid of a little OC, buy the Ryzen 5 1600 AF version from Amazon here , that is pretty much the 2600 for $20 less. (good info and discussion on this can be found on the R5 2600 FB deal link above).
