Thankyou !! This really helped : ))))))))The X boards have a slightly higher OC potential than the B boards, generally, but MSI B450 are built to withstand the supposed higher power levels of the 2nd Gen Ryzen, so end up roughly with the same OC potential as the X370. Which is higher than the usual 3.8GHz-4.0GHz most ppl OC a Ryzen to. So it comes down to whether you'll need the second slot, the fan headers, mobo software and other luxuries that you may want, the X boards tend to be better outfitted.
