Laptop specifications to use UE for VR

Hey! A very beginner question for you all: I’m in the market for a new laptop which can run Unreal Engine (I’m wanting to develop a VR experience primarily using real video footage).

I’ve looked at the specs suggested here on the website and am looking at a MacBook Pro 14" or Microsoft Surface Laptop Studio which the guys in the store seemed to think would more than fit the bill, but I just wanted to check.

Also, should the internal workings of those laptops be enough or would I still need an external Black Magic/AJA media card for video I/O?? Thank you!! I really appreciate any help.

Some pointers here, though not VR specific:

Thank you! Very helpful!
