    Pretty much what the title says. Could I plug in an external graphics card using the USB 3.0 port on my laptop, or would doing so result in really bad frame rates?

    None announced (will be surprised if they're ever announced - except for simple multi-monitor support).

    Yeah, bad frame rates (very limited bandwidth).

    You should be looking/rooting for Intel's LightPeak for these sort of applications.

    @tilleroftheearth Yeah, I figured. It was worth asking, though. By LightPeak you mean Thunderbolt, right?
    Too bad no Windows laptops have it yet, because there's no way I'm giving up my Alienware for a Mac just for Thunderbolt.

    No, definitely not a Mac (NOOOOO! :) ).

    Mac's have Thunderbolt - computers will have Light Peak (hopefully in a few months time.

    The version of light peak in the vaio uses USB to implement while Macs use PCI Express to implement, and since Apple patented it :)() then other manufacturers are stuck to using USB to implement light peak. Not sure what performance impact, if any there are when using USB as compared to PCI Express to implement.

    Apple used Displayport to transport PCIe and DP.

    Sony used USB (+ 2 optical fibres embedded in the USB port) to transport PCIe.
