macbook graphics card

Hi,


Now I've got an original white Macbook with 2 GHz and 2 GB of RAM (upgraded, came with 1 GB) with a GMA 950 Graphics Card. From what I know, this particular graphics card sucks. I can't play games that look cool like Modern Warfare, The settlers 7, Civilization 4, World of Warcraft (I think), Portal 2, and the list goes on. I'd like to know if it's possible for me to upgrade the graphics card to, say, an ATI Radeon HD 2400 or Geforce 8600, whichever is cheaper, because there are tons of games I'd like to run along with the ability to make better games as I'm a programmer/graphics designer. Thanks!

PS if there are no upgrades for a Graphics Card, are there external ones that I may buy? Just an idea.

Nope.
