It really depends on what kind of business it is that you are into.
Graphic Design
Accounting
Bakery Shop?
Instagram Model???
Also, what kind of games you want to run, because a laptop just isn't quite at that level yet, and you could be saving money in the long run by just getting a desktop.
So questions are: Which games do you want to play and how well? In which area do you work in? and Do you constantly have to take your laptop to work?
