That laptop is fine, I'm planning to buy it myself. With a CPU overclock (which barely adds to thermals and brings it into i5 range), the 6650M beats the GT 540M and is almost in range of the GT 555M. For $500 flat, and considering the general quality of the computer (fan control, touch buttons, great keyboard, etc.) its a steal. Don't ask these things on a board mostly populated by desktop users like this one, you're bound to be mislead.
