Many laptop graphics cards are not upgradeable....they're embedded onto the motherboard. So the first thing to do is determine definitively whether an upgrade is physically possible. After that, you need to find out what cards are actually compatible with your M/B and BIOS. If it's upgradeable, you're most likely looking at other GPUs of roughly the same generation, just faster speeds.


PS: Thought of a suggestion. Try finding an Owners' Lounge for your model over on NoteBookReview. That would be a good place to find any techie owners who know a lot about that particular machine and the mod options that are available.
