Game Development Laptops?

Peace in, anyway i wanna start at game development and my wealth is about 933.33$ funny huh,

right now i'm using Blender & gimp but later i'm thinking about using 3d max and unity
i saw some tutorials on youtube and one thing they have in common is that they all ways saying "get your self a good laptop" so i want a laptop or list of laptops that can run unity or 3d max or photoshop or blender smoothly,

and if i wanted to buy a new laptop what features should i look at that make a laptop run the above softwares smoothly

please i want laptop with maximum price: 933$ cuz that all what i have right now?
