Just curious to know :)

((oc_volts/stock_volts)^2)*(oc_freq/stock_freq)*TDP=aproximated TDP after OC.
Thats TDP only, since we dont exactly know power consumption of each individual chip.
and its cpu only, some more power will go to ram/chipset, but thats really a ... 2W more.

Anyway.. thanks for those equations :)

As for processing power, you should see a decent jump in performance, especially if you have a powerful video card.

Virtually zero.

??? No..... more speed(by overclocked) means more performance + energy spent, keep in mind more performance is linear to power needed ^^, or power by 2

i dont mean by processing power, wat i mean in this thread here is power, as energy needed to run overclocked processor vs the default speed
