Wich Computer/hardware?

Hello! In August I will start a technical artist education and would like to buy a portable computer but I´m not sure what is needed. (I will not only use it for graphic/programming but of course also for gaming).
So maybe you could recommend something and not just model but also wich hardware that is optimal.

Thanks!!
