The minimal requirements for a windows laptop are:
At least an i5 processor, at least 8 GB of RAM (16 GB Ram is really recommended), a SSD Harddisk with a storage of at least 256 GB(but buy an external HDD because you're going to need it) and a dedicated graphics card of minimal 2GB(more absolutely recommended).
If you're "apple-minded", Apple notebooks are also possible. All new Apple macbooks pro are okay, if they have at least 8 GB of RAM and an SSD harddrive of at least 256 GB. Also is recommended to buy an external harddrive for extra storage. If you're going to do some heavy graphics or 3D work, buy the Macbook Pro "15 or "16 with dedicated Graphics card.
Some programs that you are going to use are:
The Adobe Suite (Photoshop, Illustrator, InDesign, After Effects, Premiere Pro)
Substance Painter & Substance Designer
Autodesk Maya
Unity
