ok, i have a laptop, and i found a great solution for my slow gpu rendering times (which would be the vidock). now my question is: are there any video cards that are powerful and can go back into my laptops internal display so i dont have to use an external monitor? i want this to be as portable as i can get it. iv heard of something called optimus technology in some nvidia cards that could do that but i am not sure :/ im confused, can someone please help me?
