External graphics card!!! now that's an idea, lol. Would it connect via firewire or USB? lol Don't get me wrong I like the idea, but I don't think its possible though. There isn't much demand for it. As far as upgrading your graphics card for you laptop, I suggest you save up some cash and get a decent gaming desktop. It is just not worthwhile to either upgrade your laptop graphics card or to get a high performing graphics card for your laptop.
