external graphics card for laptops. Can I upgrade or somehow improve my laptop's graphic card , Most laptop computers use an integrated graphics chip that share memory with the ram, it is not possible to upgrade that. Slightly higher end laptops have mobile solutions with a dedicated memory such as the Mobility Radeon X600, X700 and X800 series which all have between 128MB and 256MB of dedicated memory meaning it is not taking anything from the ram.
The reason you can’t is because laptops have custom form factor cards so that they fit inside the case and since each one is different they are all pretty much custom made to fit the laptop. In some cases they even come with custom drivers so you can’t update to the latest driver from ATi or nVidia
