"There are only minor differences between the AMD X470 and B450 chipsets used on the new MSI B450 motherboards; you get two fewer Gen2.0 PCI-E Lanes, four fewer SATA ports and no SLI support. You still get Cross Fire support but only 2way, the same as the B350 chipset. What you gain is the StoreMI and Precision Boost Overdrive, so you can use the free StoreMI program with an inexpensive 2TB HDD and 256GB SSD drive to gain enhanced storage capacity and speed."
