intel hd3000 is better than gma 4500m hd. probably two times faster than 4500.
hd3000 is newer tech, performs better than 4500m, can play games at low res. cpus with hd3000 have quick sync which transcodes really fast, igp turbo boost, igp overclocking etc. read thg's sandy bridge review, it has a lot of into on how hd3000 works.
