Can i upgrade or buy a new graphics card for my laptop?
No, that GPU will not fit in! As everything is smaller in a laptop, the motherboard has the CPU and GPU hardwired (soldered or etched) on its surface making it impossible to upgrade without replacing the entire board. As you have not stated your computer manufacturer and exact model number, I cannot tell you if such a thing is possible in your case and, even if it was, it would be costly! Another option would be an external solution (although it could still be a little bit expensive). If your laptop is equipped with an ExpressCard®, you might use a ViDock 2, a high performance docking station that allows the user to add desktop graphics power without losing mobile features.
