Is the video integrated in the motherboard on Gateway M-1624 Notebook?

Looking to replace the video card on my Gateway Notebook. I have a M-1624 and specs say it has a ATI Radeon X1270 video controler. Before I begin the opening of my laptop, I was wondering if the video card is separate, or a part of the motherboard?|||It is part of the motherboard and is not an upgradable component. However, if you upgrade your memory, you may improve performance since the processor and graphics are using the it from the same pool.
