There's a reason why AMD isn't posting the minimum and average speeds of their cards like NVIDIA does. There's simply WAY too much variability with their new PT algorithms...and that IS NOT good.
On the flip side of this coin, there's a reason why this kind of article is being posted by numerous sites.....and it isn't because of sites' own internal research.
This news NEEDS to be made available because performance variances are not acceptable. Period. Someone will read a review and buy a product based on misinformation, only to find their card performs substantially worse than what a review otherwise stated.
AMD needs to just fix their crap. This isn't nvidia's fault. This is AMD's fault for having such a garbage PT algorithm which causes huge performance variances. On a funny side note, I remember when Fermi hit the market - AMD hammered nvidia relentlessly in their marketing for having a "hot and loud" card. Oh how the tides have turned.
The GTX 480 was hot and loud but at least the performance was consistent. With the 290X you're basically playing the lottery and crossing your fingers for a card that doesn't perform 15% worse than advertised...
