Wanted to let you know that I had great sucess overclocking the 320m in the Air. I used the same procedure found in this thread. http://forums.macrumors.com/showthread.php?t=904300&highlight=overclock This might help you starcraft junkies out there as it may give a 20% increase in performance. I played MW2 for two solid hours tonight without lockups at 625 / 1340. (11" 1.6 4GB) Thanks go to all in the refrenced thread that contributed to these findings!
