Vidock external gpu

does anybody know anything of vidock 4, its for housing a external graphics card for a laptop. I'm thinking of getting a setup like this but what will I need to do, do I need to buy more things or just what vidock comes with, what's the procedure for hooking it up to my laptop. I know it will need a pcie slot, but my laptop has several so no problem. I'll probably also need to get it to recognize the gpu i choose as the graphics and not what I have now. Will vidock 4 plus be big enough for a 7950 or 7970.

i'm fairly certain that it will bottleneck a high end card pretty severly(i can't say for certain)

you'll also need an external display, it won't work with a laptop display

From what I saw on youtube, people doing this, they were using the laptop display. Also what would bottleneck the graphics card and how much would it bottleneck in percent figures.

Anyone else want to chip in.

To be honest the entire thing looks pretty flimsy and not very well made. If I were you I would just sell the laptop and build a desktop because its not like this is going to be portable with that thing connected to it.
