Upgrading Macbook Pro graphics card? Help please!

Hey everyone, I ordered an Intel MacBook Pro 2.4 Ghz with 4GB of ram. I want to be able to run boot camp on it so I can start playing some PC games. Now I heard that games like Bioshock (looks amazing, I'd buy a 360 for this) should run fine on a Vista or XP MacBook Pro, but should I update to a better graphics card? Is that even possible? Thank you so much! Btw, any other games a la mode to Bioshock that can be recommended? Many thanks!

Can't be done, especially not with an Apple product.DGFreak

It has much more to do with it being a laptop than an Apple. Unless you're implying that you can't change the graphics card on a Mac Pro.
