Now that I see the processors I understand! Big difference. Very sorry I bought the C2D T6600 instead of i 330 M. I don't do much processing with my computer but I could've had a newer better processor at the same price.
Another thing. Although my laptop is new I hear a scratching sound from the hard drive. The other one I had didn't have this sound. Curiously, the sound sometimes ceases( I mean the hdd works and there is no sound, not in idle mode for the hdd). What's wrong?
