You really DONT need a monster CPU to play Dolphin games completely maxed out. Not anymore. And people would always bitch when I said that most games on Dolphin emulate pretty much perfectly. Mario Galaxy is an example of a game that is quite factually best on PC. No waggle controls... waggle motions can be set to a single button press, and of course, the visuals in 4K+ look beautiful.
CEMU is gonna be the same thing. SM3DWorld is virtually perfectly emulated at this point. In 4K the game looks like a dream.. and you can use pretty much any controller you want.
