Pro audio work (Win or Linux - don't now about MacOS) is such a tiny fraction of total PC use, so I don't think PC makers consider it at all. Even a friend who pursued a music career using Windows systems set up and supplied by experts at Sweetwater never got reliable RT audio performance. (He's now considering a Mac and Pro Tools.)
