Q9650 using 8.91watts & 8.66amps ??

That won't tell you current draw by the CPU. You'd have to put the multi-meter in series with the CPU's rails, there's really no way to do that.

I suppose if you could find a sense resistor to use on the motherboard, you could measure the voltage across it.

exactly, which means you are relying on software to guess and they are rarely correct.
