I think his point is that most people (namely 4870 owners) are going out of their way to dissuade people from buying a GTX 280, despite the fact that it is the fastest, most feature rich (and with the least problematic drivers in my experience) card for those willing to pay the extra premium.
4870 is definitely great value but it's really not that simple there are other factors in the long term such as drivers/noise/physx etc. which people just neglect to mention.
My point is that people are getting labeled ati fanboys for supporting the 4870 so what are the people who are supporting the 260/280 there is 2 sides of the coin.
