InsideHW.com posted a comparison review between HIS 2900Pro 512MB and XFX 8800GTS 320MB Fatal1ty

We all know that, after a certain amount of time since the best model is presented to the consumer market, a newer version arrives, more-or-less weaker, and takes up a spot in the slightly lower price range. A product such as this usually appears discretely, with no hype at all, and becomes generally accepted and praised for its price-performance ratio. If we only take a glance back at the past two generations, we can see how Radeons X1950PRO and X800GTO2 sneaked onto the global market and became very popular in no time. When we received X1950PRO's inheritor, the HD 2900PRO, for testing purposes, no one ever even mentioned how great a product it is supposed to be.
