lowering the FSB

[Peter Ganzhorn]

If you don't need the power, why not buy a CPU that is designed to save 
power such as the VIA C3? Or are there any recent Intel CPUs for 
Desktops designed to save power?
BTW: There is no difference between GMA-3100 or X3100...but I think for 
Desktop boards the integrated graphics chip from Intel is called X3000 
and is faster than the "mobile"  X3100.
