Well they're comparing a 9500GT (from text) and using a screenshot from a 9600GT. These are old cards. What they're not saying is;
"if you have a 9800GT or better, you don't need our GTX660. Like, that GTX 260 you've got, yup, it'll do or that GTX460 you've probably got, yeah, that'll do fine."
They're doing nothing wrong really. And the screenshots are different because it says in the PR you can play it with a 9600 but just not with all the bells and whistles.
Meh, no big deal.
