Provolone

I don't know much about GPUs and I've been doing a little research because I want to make my laptop VR ready. I now know that I can't simply switch out the graphics card in a laptop so I think my only solution is an external card. My laptop stays plugged in most of the time, I only take it to class and sometimes a friend's house. Heres the specs Computer: Laptop, Dell Inspiron 7559 Signature edition GPU: GEFORCE GTX 960M CPU : i7-6700HQ 2.60 GHz RAM: 8Gb OS: Windows 10, Build: 14393.693. 64 Bit i would just like to know if it'd be worth it to have a eGPU setup instead of building a whole PC. Thanks!
