')For PC's, I'd say at least setting the monitor power-saving mode helps a lot, especially for cheapos like me who can't afford (and don't want) LCD panels and have stuck with CRT's. Set to 5 or 10 minutes, and it's off.
The PC itself takes a lot less power than the monitor especially if you're running anything newer/better than Windows 95/98. Windows NT and XP (and 2003 should as well) come with a "System Idle Process" that issues the HLT instruction (HALT, actually) when doing nothing in particular.
Oh, and if you're actually going to buy a new CPU, avoid the Intel Pentium 4's, *especially* the P4E's - they're the V8 energy guzzlers of the processor world nowadays. The AMD64's are cheaper, run faster in most applications except XVID, MP3 encoding (who does that all the time anyway), run cooler and use much less energy.
Mine's an AMD64, it runs at 41 degC idle, 44-46 degC running 3D games, and up to 56 degC XVID encoding. Intel P4E's typically run at over 50 degC *while idle*. And heat up over 60-70 degC, guzzling way over 100W at full throttle.
you can do a little better. if gaming is not you thing i recomend geting one of those via cpu's they use as little as 7 watts.
clicky large passive heatsinks for your cpu and video card should also reduce power usage though you will need a case that has good ventilation.
edit: i forgot to mention that even the us army is condsidering switching to open source software cause on avergae it is cleaner code thus takes less power to execute.
