Got ya, makes perfect sense. Well what you could do is if you have a GPU just run the GPU and not the CPU...just kick on the CPU when your not using it maybe? That is what I did before I built this recent PC....and GPU mining tends to not effect your daily usage as long as its not gaming and GPU extensive software. Totally get you now, that is a good question. That is why they have the checkbox option on your devices, just in case you don't want one mining but no limit on how much power it uses sadly, maybe in the future
