I'm looking to buy a gaming laptop for VR.
Moving abroad and don't want to bring my PC with me, but I don't know much about laptops.

Will a Razer Blade with an RTX 3080 be good for VR? 
I understand that it will be a hell of a lot better than my GTX 970 desktop, but as its a lot of money I want to be sure it is the right choice.

I can't understand how they can get such a powerful card in a laptop so thin and for it to be capable. Surely a 3080 laptop cannot compare to a PC with the same?
