So at 2,2 GHZ you have 100VA power consumption in idle and 180VA under full load. With 2,6 GHz you have 120VA in idle and 200VA under full load.
You only had to change the Nb voltage +0,1V to archive those high NB and HT frequencies so i assume a similar power consumption.
This system runs more power efficient (GHz vise) if overclocked to 2,6GHz.
As my 9500 still did not arrive and the M3A seems to be delayed till 12/12 may i ask for CnQ enabled (or lowest possible multis set) idle power consumtion at 200 vs 240 MHz HT?
HD 2600 XT's power consumption here in idle ~30W. So using an HD 2400 XT or pro instead should substract ~20W from the power usage resulting in 80W consumption for the whole system w/o CnQ.
