The first article shows that the flagship-to-come from AMD/ATI is hardly the power of a several-months-old NVIDIA product (the GTX TITAN). Although I'm happy that AMD can achieve this, it does not make them ahead of NVIDIA in my books. But you are right that NVIDIA may not be miles ahead of its competition (or should I say sole competitor?) anymore.
The S|C article is interesting read, as usual. And they are often more than _semi_-accurate :-)
