We have this discussion also with magazines here in germany. They have also rated pro nvidia as they are sponsors of the magazines. But in forums, where people are skilled with gfx cards, even the nvidia buyers say, that the 6xxx series undoubtly lost against ati this time. Not much of a problem as both cards are playable, although you buy half of a card at nvidia. So they should be half the price of ati cards.
Yes 660Ti will loose with few percent, but that review pointed out that AMD have problems with drivers and AMD admitted that.Even if fps is bit higher in general it fluctuate a lot more which causees stutters even if fps is good.
And AMD 7000 are much longer on the market.

And here that is explained in simple words that anyone can understand.
Look at 4:15.

And AMD responded to that.

The most intriguing revelation in Baumann's correspondence, though, concerns one specific technical contributor to the frame latency problems on HD 7000-series Radeons based on the GCN architecture: less-than-optimal memory management in software.

Additionally, when we switched from the old VLIW architecture to the GCN core there was a significant updates to all parts of the driver was needed – although not really spoken about the entire memory management on GCN is different to prior GPU's and the initial software management for that was primarily driven by schedule and in the meantime we've been rewriting it again and we have discovered that the new version has also improved frame latency in a number of cases so we are accelerating the QA and implementation of that.
So a specific portion of AMD's driver code needs some additional attention in order to perform optimally on the year-old GCN architecture—and AMD has accelerated an overhaul of it after discovering that the new revision can alleviate frame latency issues. Wow.
