i really doubt you can upgrade it
This is not true, in many cases. If it is upgradable the standard is most likely going to be either MXM 2.0 or 3.0 for the mobile gfx card. When upgrades are possible the card are often readily available via online vendors or the manufacturer (probably not the cheapest route). Or Ebay in a pinch or if the cost/availability is better.
What manufacturer/model of laptop do you have? That information is necessary to determine if an upgrade is possible or feasible.
