My daughter wants to buy a laptop that is suitable for gaming. Examples of
games she would play are:
Neverwinter Nights 2

Star Wars - The Best of PC

Grand Theft Auto - Vice City or San Andreas

All of the retail laptops I have seen come with video cards that typically
share the memory with the computer up to 128 Meg. If I go to Dell, I can add
a card with 256 or better ram. If I bought a laptop with a core 2 duo
processor and 1 gig of ram, would these retail store laptops be suitable for
playing the above games? Is it necessary to go up to the separate video
card?

Thanks for your experience and advice.
