This may be an incredibly stupid question but here's the deal. I recently bought a macbook. the only real reason why I didn't get a macbook pro was because the macbook I bought plus the extra ram I bought and installed myself was something like $700 cheaper than the bottom line macbook pro (more to upgrade it to 4GB of ram myself). I couldn't really justify spending all that much extra for just a video card and a slightly bigger screen. I recently started playing world of warcraft and it runs pretty well on my macbook however I recently saw a friend playing it on a macbook pro and I became envious of how smoothly and everything the game ran. the only real difference between my macbook and my friend's macbook pro seems to be the video card. So here's my question, I know for like $150 I can buy a 320GB external hard drive so are there external video cards that I could connect to my macbook through a usb or firewire port? If such a thing existed it would have to be pretty cheap. So is it possible to get an external video card that's about as good as the video card in the bottom line macbook pro for a price that's not really much more than around $100?
