some games "lag".

Well, overclocking GPU is much easier, you can done it in your os, no need to go to bios, I overclock my GT555m with nvidia system tool and it works out pretty well for me . I use nvidia system tool on the card because it will save ur settings and every time u change the values it will always ask you if you want the setting to load up on the start of windows. But overclocking cpu, on the other hand, is a different story....

Is this "lagging" the same thing I'm experiencing when I'm playing Jak 3? For me it's not "lagging" like you'd see on an mmo where nothing moves and then suddenly things move again, it's just like everyone's voice and movements are slightly slowed down and drawn out, as if you're watching them walk around in slightly-slower motion than normal.

Does this mean I have to overclock? I've never done it before. I have an intel i7-2720QM CPU @ 2.20 GHz with 4GB of RAM.

you have a latop and thus you cant overlcock.
