The whole of DF is also pretty consistent in mentioning how 30%+ differences in resolution means little (it used to be a world away though), while 1-5% differences in fps should always be a deciding factor. Going by the general sentiment in this thread, one wonders if DF's emphases are based on reality.
Look, if you're just going to pull up a bunch of articles dark10x didn't write in an attempt to claim that DF is a single hive entity of writers hellbent on making MS look good, and Sony look bad, then you're wasting both of our time here. This is a dark10x article, pointing out aspects of the performance that dark10x always talks about. There's no smoking gun here at all.
Despite all that though, I am going to address your "it used to be a world away" comment anyway. As resolutions increase the perceptible differences between them decrease. It's a LOT easier for me to notice the difference in resolution between games like Halo 3 or PGR3, than their follow-ups Halo Reach and PGR4. Also, taking an article where not only is the resolution higher, but the framerate constantly floats a good 8-10fps higher is hardly useful by comparison, as the framerate is covered in that article too. If the fps performance of the two were swapped, you may have more of a point (still not much though, considering that dark10x had nothing to do with that article).
