To test power consumption today we use a Keithley Integra unit and we measure power consumption from the VGA card inputs. We measure results in this state while gaming in Crysis Warhead.

We also measure overall system drain from the socket with a calibrated meter. We measure this while running the final CPU/GPU intensive test in 3DMark 11.

In 3DMark11 the system with two overclocked GTX680's demands 607 watts of power at the socket.

This may seem like a lot of power, however regular readers may remember that a system we tested, almost identical to this (image above: 3960X EE clocked to 4.8ghz), with two GTX590's in Quad SLI. This configuration demanded 929Watts at the socket.
