A piece to install a graphics card on your laptop, even if it's an older generation. The benefit is that you can install the graphics card on top of it and use it with your laptop, but it takes 10% of the card's performance, meaning the card runs on your laptop at 90% of its power. (Also easy to install and useful for someone who doesn't want to spend too much and has a limited budget.) Negotiable (Exp GDG PCI-Express to) No way
