8800gt over-volting wattage increase?

[Gautama2]

Can anyone with the equipment test how much the power consumption increases when the 8800gt is overvolted or link me to somewhere it has been measured?

I can't give direct numbers but there was a review of a 600 vs. 650-660 and it was only 4-5 watts more at load. The whole card's TDP is 105-110 watts and it increased the core 10% which you would think is 10 watts more but a lot of that goes to the 512mb of memory and the components on the PCB. If you compare 600 vs. 800 core it would only be roughly 20 more watts load at the most.

If I run across the review again I will link it, but there have been so many I doubt I will.

No, not overclock; overvolted. Power usage inceases much more with voltage than clock speed.
