I don't think the PCGH article setup is bad, I mean it clearly shows that at times even the GTX280 somehow loses to the 4850, such as my Oblivion example.

The PCPER article should've clearly stated the 8800GT and 9800GTX were OC'd versions to eliminate confusion, but I guess they did a rush job to put the article up. So either way you look at it though, the 4850 hangs and even beats OC'd versions of the GTX.
