you cant oc the cpu. only video. however you can always tweak your windows and start up items so your pc runs as fast as possible. My 3d scores are in my sig. i have 1 of the first 7700's made so i have the old style ddr2 6800. And im the dude with the cooling mod. I would recommend some sort of extra cooling if you overclock any part of your lappy. read my thread and decide if my mod is for you. keep in mind AW will void your warranty if they find out you OC or mod your lappy.
