Thank you riptide for testing this out - I really should buy myself the kill-a-watt.

Is my math correct using a 6700 with stock of 2.66ghz and 1.35V stock and OC'd to 3.4ghz and 1.45V:

65 TDP x (3.4/2.66) x (1.45/1.35)^2 = 95 watt increase due to OC

The default watt consumption at stock everything is 65 TDP x 1.35 = 88W
