I haven't really played it, but sometimes the GMA 950 can pull out surprises... but it's usually more a really well optimized game that does the magic.
Too bad I just found out my netbook doesn't seem to be able to playback 1080p video files either
Maybe next year there will be a cheap netbook with decent (read: plays most games at "low" settings at 1024 x 600 without dropping below 20 FPS) 3d graphics?
My non-netbook Lenovo X300 has some relatively recent Intel Integrated Graphics. Can't even play HL2 at low res. I get about 2 FPS in L4D2 at bare minimum settings, 640x480. The most intensive game I can play on it is Plants vs. Zombies, and even that slows down when there's a lot of action onscreen. I doubt a netbook would do much better.
