Uh...actually...
The Ars article, last I read it (with their edit) said that Intel was already using NVIDIA's Intellectual Property in Sandy Bridge. They didn't use the word "patents", and while it may be nitpicking, "Intellectual Property" could mean anything from "patents" to "designs" to full on schematics to full on NVIDIA GPUs as all of those technically fall under the definition of "Intellectual Property". That said, I wouldn't put it past Ars to be, as anyone here would be, overly stoked on the news to the point of reading far more into it than there is to read into it.
