The latest GPU-Z (0.5.8) has an interesting new feature that scores your gpu. My Gigabyte 7970 scored a 70.9%. This score apparently is based on how much leakage the chip has so the higher the % the less leakage there is. Im not sure how they go about figuring this out but I think it has to do with the ammount of voltages applied.
