Can I Upgrade?

Hi, im sorta a nub when it comes laptops and installing hardware so i figured i'de ask here. I recently bought a HP Pavilion Dv7-1464nr Notebook PC, and i was wondering if theres a better graphics card i can purchase for it and if its possible to install it.

I wasnt sure because most parts seem to be built into the laptop and look either difficult or impossible to replace or upgrade without an exact size match...

I plan on playing some pretty high req. games so i need the best graphics card this laptop can handle or is compatible with

 

No you can't upgrade the video card on that laptop.
