The whole review was just benchmarking. When I read the review, I know the cards is as fast as a 4870. Nothing more. For the rest, I have to trust the advertisement or other reviews, which are mostly done on Windows and have to trust, that the behaviour in Windows and Linux is the same.
So a company gets a Phoronix Award for bringing out new midrange hardware which is as fast as last generation performance hardware. Ok. So please give AMD and Nvida awards for their previous generations of hardware, too (just kidding )
PS: And of course its fun to make AMD-fanboys upset (Kano is becoming too friendly... )
