What's faster, my black dodge charger r/t sedan with 4 doors, or the same year red dodge challenger r/t sports car with 2 doors. Actually the sedan with 4 doors is faster than the sports car with 2 doors. Regardless of color.
Gaming is a label. A gimmick. For most applications, an Asus Prime board is just as good as the ROG versions, in some cases its far better suited and much cheaper. But gamers want black/red not blue/white (for the most part), so things labeled 'Gaming' are aimed at a more specific target market.
A 'Gaming' chair might be sleek, red/black and have speakers in the head area, but my wife's 12hr rated ugly brown office chair is far more comfortable for long term sitting.
So it's going to depend on exactly what the expectations and needs are for the user. If a 'gaming' mobo has the fan ports, USB, ram, audio, Lan, storage etc that Op pc needs, then that's that. But if a cheaper, non-gaming designated mobo will do the exact same thing.....
