Just did a side by side test with old 2.26G model with new 2.4G model. Speaking of 3DMark 06, My 9400M scored 2170 while the 320M scored 4748! FPS during test was usually 2x or more. That makes a lot of games playable on 320M while not playable on 9400M Compared to old 9600M GT model, according to Notebookcheck.net, it averages 5163, and GT 330M is just 6539. So, 6539/4748=1.377, only about 40% increase going up to 15" models? Interesting. Edit: Environment: Both Windows 7 Ultimate 64 bit, 3DMark 06 1.20 basic edition Specs: 2.26G version 4GB DDR3 (Crutial 2x2GB), HDD: Hitachi 7k500 500G 2.40G stock configuration.
