"ROG", "STRIX" don't contain the word gaming. Neither does "AORUS". The only company effected here is MSI.
Yes, because they only use gaming on video cards. I absoultely don't have an Asus mobo that was one of the last amd 970 chipset based boards made by them (with a m.2 and usb3.1 no less) that has the name "970 Pro Gaming Aura".
