OCC has published a new review on the Sapphire HD 4890 Atomic Edition

The Sapphire HD 4890 Atomic Edition is a ready to be a prime time player. In the single GPU field, the GTX 285 has been the undisputed king of the mountain, and usually carries the title of the fastest single GPU card on the market. It now has competition in this category, as the HD 4890 Atomic puts a serious dent in the performance gap between ATI and Nvidia. So much so that when pushed, the Atomic HD 4890 even pulled ahead of the factory overclocked GTX 285 in more than a couple tests. Not quite there, but getting much closer. What makes this card appealing to me is the fact that Sapphire has once again gone out and produced a video card using their own PCB, with improved voltage regulation, added their own Vapor-X cooling, and delivered a factory overclocked video card that serves notice that ATI will not allow Nvidia to rest on its laurels. Usually you wait months for a card like this to appear, but Sapphire wasted no time bringing this one to market.
