Better late than never, but here's the way it works with CPUs....
Simply put, you're adding more cores, so it will eat more power and make more heat WHEN RUNNING FULL OUT. When you're running a very low load on it, it will hardly use any power and produce virtually no heat, so the situation where you are OK with the X2, i.e. watching a movie or something, it will STILL be silent. When you're doing something really intense, then, if you LET it, it will ramp up speed and get a bit noisy.
Think of it like this;
If you have a car, you will notice that full out at, say, 5000 rpm, then it will be really loud. When you're cruising at 2000 rpm, you can hardly hear the engine at all.
@Thatguy: what are you trying to prove by overclocking with air cooling? That you can make your computer sound like a vacuum cleaner without setting it on fire? You didn't say anything that supports the OEM cooler actually being decent. IT IS STILL A PIECE OF CRAP and it still makes a NASTY noise. A good heat sink with a large and slow fan can cool the CPU *better* while remaining SILENT. Even overclocked.
You are best suited with Intel ATOM + nvidia ION.

Of course you can downclock the cores, but current amd energy management is two levels lower than of intel. The noise can be compensated by cooling - its not a problem. But your energy bill cannot. Energy efficient CPU or energy efficient video accelerating GPU are vital.
The mentioned phenom II is good for actual active work - ie recoding ,compiling, calculating etc.
Uh, well, good luck finding next prime number with you Phenom II...

You get 6990 or GTX 580(better driver) with Phenom II and you have a monster that when IDLE - chomps triple the amount atom uses at 100% LOAD! Its often cheaper to buy such machine, than to pay exactly the amount in electricity bill at end of the year for using performance machine on such loads!
The cfg is perfect for HTPC and light games only. I don't posses ATOM ION, but a friend of mine does and he reported very good performance in Urban Terror. Means idtech3 or equal games should not be a problem.
FWIW I have a P2 965 running at stock clocks 3.4/2.0 @ 1.2375 Vcore, 1.1250 NB. It is stable and uses far less power. Sadly I do not remember how much.
My Atom 330 system uses ~42 - 43 watts with 1 7200RPM drive under a full CPU load. It also takes 8 hours to do 1 of 2 passes on a 1.5 hr SD video encode to Theora.
If you want, you can suck it up and try to wait for bulldozer with their powergated cores and improved TURBOcore
Phenom II 965 normal and 1.2v undervolt, without vga.

Lets take a version you watch one movie daily - thats 2 hrs/1 day.
Europe best energy cost: 10€/Month + 0,20€*kW/hr
For a year thats: 120€ + 0,20€*kW/hrs
For undervolted AMD Phenom II always idling at watching movies vs always full load ion:
0,20€*0,026kW*730= 3,7€ year
Realistically I seriously doubt phenom will idle at movie play. Or igp/discrete gfx card it uses will idle, so its absolutely best case.
ion system cost is around 100€. Do you need it - I think yes if you use around 4hrs a day for 3 years.
Uh sorry, I made a mistake above. Thats not 111W, thats 106W.The rest is correct.
