Also, just to point out that you can't compare emulation with regular pc games. This is because what emulation does is it tries to be as similar as possible to a console, which is completely dedicated for games and uses its own language to play these games. Because of this, this language has to be transferred and read into something that a regular pc CPU can read and thus puts a lot more stress on it, unlike pc specific games where CPU doesn't really matter and mostly run with your GPU's specs.
TL;DR: pc emulation is much more stressful on hatdware than regular pc gaming
