My opinion is that regular in this sense refers to gamers or casual enthusiasts who are mining with less than 13-GPUs in a single mobo at home. Anything below that and i believe they are mining inefficiently to the point that they will be the first ones to go when mining becomes unprofitable altogether.

GPU mining is now about maximizing your mining revenue while reducing your electrical costs. ASICs are great at this and unless devs do something to dennounce them, ASICs will take over the entire crypto-mining scene.
