There are several reasons to buy a gaming laptop over a desktop, but the biggest two would be portability and desktop footprint. That's what makes MSI's GamingDock such a curious proposition, since it trades both features in exchange for more raw power. Essentially, GamingDock is a big-ass box with a PCIe x16 slot that's designed to take a top-of-the-line desktop graphics card. Then, all you have to do is dock your GS30 Shadow into the top and you'll be able to dump the pixel crunching on the more heavyweight hardware. There isn't much more to it than that, but if you're interested, the GamingDock will launch in January at a price that's yet to be decided.
