Desktop Graphics Card on Laptop using Mini PCI-E

Recently I stumbled upon this video It's adapter that allows you to hook up desktop graphics card to a laptop. Has anyone had any experience with this? I don't think I'm going to try it but I'm interested in what other people think.

To me all those solutions just seem like they aren't worth the effort

You'll be losing a lot of bandwidth with those, not a very practical solution than just buying a laptop with a mobile GPU. Plus not a lot of laptops today have built in mini PCI-e slots.

They have, you just have to remove your wireless + bluethooth card and use a dongle.

Interesting if you are a person that only wants a laptop and wants to still game and do it decently. It is definitely cool in a pc nerd sort of way so if I had money to burn I might do this.
