I would have thought 'Gaming' (capitalised as it is a product name) would apply more to the Z170 motherboards, since proper gamers would likely want to use an unlocked CPU and overclock it. I don't see the B150 chipset suitable for such purposes. I guess MSI wanted to make perceivably higher quality versions of these motherboards utilising lower end chipsets, since typically these chipsets are combined with lower end components. I still see 'Gaming' as a bit of a misnomer though from a branding sense. It's good to see though some better quality (at least, as it appears) lower end motherboards coming in though!
