However, i can add this:
Intel Z68 chipset 6.1W
AMD 890FX chipset: 18W
so there you save another 8.568 kWh/month on top of the 21.6 kWh from the CPU alone. Still not enough to justify it? Didn't think so

TDP generally is the actual amount the chip uses (at stock speeds). And it is in the manufacturers best interest that it is, because computer/heatsink makers use this number to design the heatsinks for the chips. If they under-value this number, then heatsinks fail and someone gets embarrassed. If they over-value it, then they just look really inefficient. It is worth noting though that this number is not exact, but really close.
