What is the best graphics card for a laptop? and how much would it cost me?

Answer:

The best graphics cards currently available for a laptop are the nVidia GeForce Go 7950GTX, or the ATi Mobility Radeon X1900 for gaming. For mobile workstations, the best cards are the nVidia Quadro FX3500M or the ATi Mobility FireGL V5200. You probably won't know how to buy these individual cards, but Biohazard Computer Systems offers the Outbreak SLi, next to two GeForce Go 7950GTXs in SLi, and Fujitsu Siemens have the AMILO Xi1554 with the ATi X1900. As for the workstation cards, Dell's Precision M90 workstation have the Quadro FX3500M GPU, and IBM/Lenovo offers a Thinkpad T60p model beside the FireGL V5200. Hope this helped.
Graphics cards are built into the board on laptops, you help yourself to whatever is fitted.
If your conversation about upgrading your card for your laptop first you should get sure that it can be upgraded, since many laptops can't enjoy their graphics card upgraded. Like mine :{
the only changable parts on laptops are:

1. LCD

2. Hard drive

3. hit



anything else is not changable or upgradable
