I got an alienware laptop area 51 m5500 with:
Pentium M 1.73GHz
1GB of RAM
Windows XP
Nividia Geforce go6600 (ordered yesterday)
Realtek HD audio

I am aware that the series of Nivida cards on laptops "may work but are not supported" but i know that some people can play Bia on laptops so it must be possible. Plz tell me if my system can play the game ty in advance

You should be good. I have a laptop with a 256mb 6800 GO, looks/works beautifully. Just make sure your drivers are up to date.
