Help I need a gaming laptop?

Hey, looking to get a gaming laptop that can run games like witcher, MGS V etc on high settings or close to it.

I know desktops are the way to go in gaming, but I m looking for something mobile. Could both of these run recent games in good to high settings? If not which would could? Thanks.
