duo core 2 energy efficient

cyberstar

I read somewhere that duo core 2 processors are energy efficient and saves up to 40%. Does that mean I will use less power than and ordinary PC and save on my electrictrity bill?

I think this depends on the Watts of the PSU.

Graphic cards use a lot of energy as well.

Yes the Core 2 Duos tend to be more efficient. In saying that a new PC compared with one from 3 years ago will probably still use about the same amount of power as graphics cards now use more power.

Out of interest does it make a difference whether the graphics card is shared (like my laptop which has 128 MB shared graphics) or separate?

Seperate will be more energy.

Saying that though that doesn't mean its not energy efficient
