4870 & 4850 crossfire-x analysis
Power Consumption & Temperature
To measure power consumption I used the Seasonic Power Angel, which bridges the power cord from the power supply and the wall outlet, and displays a reading on the screen. I used three programs to measure the power consumption: Far Cry 2, GTA IV, and Crysis.

To measure the GPU temperatures I used GPU-Z and had it log in the background while looping the benchmarks.
