I just bought a brand new Fujitsu Laptop. i need a new video card can i change it?
 

I just bought a brand new Fujitsu Lifebook A6030. I want to run World of Warcraft but the video card which is a Mobile Intel 965 Express Chipset Family has trouble running it smoothly and clearly. My question is can I replace it since it is not an integrated chip and if so how to I go about doing that? I'm a pretty big noob when it comes to computers but could i be trusted to follow a step by step and install a new chip myself? Any help will be appreciated! Thanks so much...
