Laptop Gaming Questions

[Keiiko]

My friend has gotten me into online gaming. It's not high demanding games.One game I've played often is Gamigo's Fiesta. But my friends said do to my graphic card I would either need a new laptop or a new card. But I don't know anything about graphic cards and such.
The laptop I have is an ASUS and the graphic card is a AMD Radeon HD 6290 I've googled it and heard that's it's not very good for laptops. Can I totally change the card to a NVIDIA GForce (sp?) I found on the net for Asus laptops? Or does it have to stay a AMD?

There are very few laptops that can actually change out the graphics module, roughly 90+ percent of the time you are stuck having to upgrade the entire system to get a higher end graphics chipset.
