I've currently got a Hp Envy DV6-7200ea which is running an integrated intel hd graphics 4000 with a dedicated Nvidia Geforce GT630M installed. I've heard of eGPU's like ViBox or something and I'm not exactly sure if it will work for my PC. If anyone does know, what is the best graphics card that I can upgrade it to (and yes, I know I will need an external monitor for this) which is compatible with my laptop. Also, is anything required in the laptop to run this like a specific slot or something? And if I don't have this slot, would there be a sort of adapter which allows me to connect it via USB or something? Some insight would help alot! Thanks.
