i m also using the same GC and I don't think it is suitable for games like Cod5 coz my laptp lag.
bsides, no use overclocking also because when overclock 3dmark 2005 just give abt 2300 points. very low
and laptop become very hot. besides this version of GC hav some prob with da gam of the processor. if too hot, glue will shift and then need to repair.
so no use overclock. I tried. U can try. but b careful..........
