I don't have a problem with the article.
People are saying they are too focused on price, don't know the tiers and replacements and relationships, then naming schemes etc...
The bottom line though is the bottom line. Who really cares what the gpu naming scheme, number, "tier", "tier position" is etc.etc.etc.
unless all you want to do is rip or praise the PR scheme departments or amd or nvidia?
The bottom line cost vs performance is what really matters to everyone.
They could call it the blue cheese moon card 93970 dash 42 and no one would really care if it rocked for it's price.
The point the article made for me was the 5850 was a very good buy thus has long legs and lasting value and perhaps the 7850
is not so great and did not really show much progress at all considering the years that have passed.
A person cannot go by claimed tiers and naming schemes. Sorry.
A person has to go by the price and the performance.
If they called a card 2450 Monkey Writer and it outperformed the 680 and cost $300 new right now... it just does not matter.
The article was somewhat painful as it showed performance movement is not so good, thus confusing discussion and denial has been in order. Time for a drink.
