Laptop GFX card q's

Ok so I have a Sony Vaio VGN-CR590 which came with a horrible graphics card. I wanted to change it but I have never changed a graphics card before. I opened up the laptop to try to figure out where the graphics card is but i am clueless.

Theres the image of the insides. By the looks of it can you tell if I actually can change the graphics card?

Oh and also does anyone have a recommended graphics card? I only really play wow which usually lags during bigger battles and according to a box i have it. I'd like to have 512mb atleast for a new game I got and dont want to spend over $200! Thanks!

 

idk where the graphics card is on that computer but you can probably find a very capable one for $100

 

Well I just checked and my graphics card is a "Mobile Intel® 965 Express Chipset Family."

The chip to the right of the fan does say intel on it but im not sure if its the processor.
