I recently bought a second Asus GTX 670 for Sli and I noticed that my new card consumes about 3-5% less on idle and over 10-15% less when loaded compared to the old 670.
I swapped their positions and the new card still draws less power, although with higher temps when it's in the top slot, it's still cooler than the old card in the top slot.

Does this mean my new card is of better quality or is my old card aging? I've only had the original card for about 3 months
