and of course, there are integrated solutions.
the ati320M (i think that's it) and the intel extreme graphics. both suck for gamers, but if you dont game, you wont care.
the ati320M gets around 1500 in 3dmark2k1. dont know about intel extreme graphics, but it should be about the same. (with both a 2.4ghz celeron and an amd 2200+)
i have a centrino system with 9200 (9000, sorta =) and thath gets me about 5500 3dmark2k1.
