Its an External graphics card box for notebooks. Basically plugs into your PCI Express slot (i think), and you can use Desktop Graphics cards on it.

This sounds great for laptops where you can't really upgrade the graphics card once you buy it (unless you're a real techie). Was wondering if anyone has experiences with it? Thinking I might just buy a laptop with good CPU power but little or no graphics card and then use ViDock for gaming when I'm at home, but I'm curious if anyone has tried this thing before
