64mb Intel Graphics Card

I got this card since I have a HP computer, not even a card, its integrated. Anyway, its called: Intel Extreme Graphics with integrated memory of 64mb (using Intel 82845G/GL/GE/PL/GV Controller) and I was wondering if there is anyway to boost its visual output? When I play NFS2 for example, the graphics is really lagging. Sometimes it happens to go faster but not as smooth as you want it to be. If you guys know this integrated video, please tell me how if possible if I can make it better by changing settings maybe. I already have the latest drivers and my computer system is working fine.

btw, anyone know how much is a Nvidia Geforce 4 MX 440?
