Can I change the video card on my ASUS X53E-XR3 laptop?

I just but it, it has a core i5 processor with 6gb of ram and 500gb HD, any opinions or comments about this laptop? I also would like to know if I can change the video card, or it has a good one already?|||Afraid you cant on a laptop, desktop yes, laptop NO.|||It is part of the motherboard and can not be changed.
