I am planning to buy a laptop that is between portable and gaming capable. Most laptops I see have either GT540 or GT550 or GT 640. All of them has 2GB of video memory. Is that memory dedicated or shared? I already checked their performance on www.notebookcheck.net Do manufacturer's prefer mobile Nvidia GPU than AMD? Most laptops I see are equipped with Nvidia GPU.

When you see the term 2GB of Video Memory, it's likely dedicated. Most of the time, the review will mention shared video memory where applicable.
