Partly yes don't you think? Don't tell me mainstream now only contains some specifics that the OCUK forum has decided upon. Gigabyte even keep the Gaming in the title as do MSI.
Not at all.
I find is rather amusing, though also sad, that you fall (fool?) for the marketing words of manufacturers. Aesthetics of the motherboard doesn't affect the functionality of the PC. But it does appear that people look at boards and think "Ooo RGB, it must be good for gaming" or think because it's got "Gaming" in the title that they're going to be better at Overwatch or CS:GO or whatever the kids are playing these days.
