What is the best laptop for me?

Soon i'm gonna be in college, I'll be taking game development, in game arts, i think it will have 3d design, rendering and stuff, what is the best laptop for it? I plan to buy lenovo legion y520

You want something with a lot of power. If you're doing 3D rendering that's fairly resource demanding. Video editing is one of the most resource demanding processes a person can do on a computer. 3D rendering is up there as well. Some more powerful the computer the faster it's going to compile your projects.

The course should be able to suggest minimum system requirements needed.

You don't want that laptop. It has a horrible display. Read the reviews before buying it.

Just look for the top cpus as you need them for multitasking. I7 seems very good. Also a good graphic card. Moreover, look for as much as possible RAM. You need also enough hard drive space.
I checked your laptop and i think is one of the best choise you done.

You need a strong multi-core processor, lots of RAM, and a dedicated GPU, so…
ASUS VivoBook Pro N705UD-EH76 is good
powered by i7-8550U, 16 GB RAM DDR4, 256 GB SSD + 1 TB HDD, and GTX 1050.
