You're wrong :) Nowadays the power consumption of a CPU is more than the rest of the machine altogether (including hard disks, etc.). On my P4 2.8GHz HT CPU, I've measured the power consumed by *the entire computer* more than doubling as the processor went from idle into 100% load. Of course, this doesn't include a monster 3D card, is it could very well consume something close to the processor when doing a lot of 3D operations. -- Paulo Marques - www.grupopie.com All that is necessary for the triumph of evil is that good men do nothing.
