Ummm. Am I misreading this? I thought in a GFLOPS/Watt rating, the higher numbers are better. So the Titan is the best of the three listed cards.

Now this may be completely wrong, but let's take a stab at costing this.

With a difference of about 55 Watts in the TDP rating between the 7970 (195) and the GTX 680 (250), doesn't that equate to roughly 40Kw of power consumption monthly? (55*720hours in a 30 day month) Just taking a stab at a 12 cents/KwH price for electricity, that's about $17.00 monthly to run the 7970. And $5 a month more to run the 680. Wasn't the TDP of the Titan supposed to be about 235? Which makes it about $3.50 a month more expensive to run than the 7970.
