Power Consumption To emulate real-world usage scenarios, we record mains power draw both when idle and whilst playing Batman: Arkham City
Temperature To emulate real-world usage scenarios, we record GPU core temperature both when idle and whilst playing Batman: AC
Noise A PCE-318 meter is used to record noise levels when idle and whilst playing Batman: AC
Overclocking Pushing the graphics card as far as it will go, we increase speeds and re-run the Crysis 2 benchmark

Notes

We've added the card to our high-end graphics line-up. Also included are the GTX 680 variant of this card and, far more interestingly, we've included the numbers for a couple of pre-overclocked mid-range cards from the last generation, tied together in SLI. The ASUS GeForce GTX 560 Direct CU II TOP, as reviewed here, represents the same level of performance as exhibited by a GeForce GTX 560 Ti. We know that many readers opted for either the GTX 560 or Ti, so combining two, in SLI, should give us a much better understanding of how an overclocked GTX 670 performs against the mid-range stars of the last generation. What's more, the latest NVIDIA drivers, 301.42, provide support for these older cards, along with speed-up boosts for SLI.

In the ensuing graphs we've highlighted the £350 ASUS GTX 670's TOP's performance in green and shown the SLI'd GTX 560 TOP's in shades of red. The two 560s, combined, are available for some £325, making the comparison valid. Also, it provides the numbers for folk thinking of adding a second card of this ilk; we figure they'd want to know if it was worthwhile going down the SLI route or ditching the first card and purchasing something like a GTX 670.
