CPU mining is not worth it, period.
GPU mining might be worth it but not when you have to buy new hardware.
And since you mentioned using a notebook it is even worse since you can't dissipate heat effectively and might cause overheating.
Besides if you have read up on the forums all mining rigs are built using desktops since mobile GPUs are usually underpowered.
I'm using a Laptop, you mad bro?
Actually, I'm kind of mad.
