The HD 5000 series is well entrenched with a full product stack that fills just about any need and price point. With that full of a product line, why populate an already stacked deck with another card? For the same reasons people buy high performance cars. Sure you have options that go from the mundane grocery getter to the top of the line with all the luxury features. Then there are the specialty models that offer increased performance and it's that added flash that gets them noticed. Flash and performance are selling points that make a product appeal to a more exclusive club. For video cards, that group equals gamers and performance and flash sell to a group with higher expectations of performance. Sapphire does a good job of building cards to fit this niche with their "Atomic", "Toxic" and "Vapor-X" line-ups. Each of these lines add increased levels of performance and cooling as well as Sapphire's own proprietary construction.The Sapphire Toxic HD 5850 2GB is a card that contains the whole ATI HD 5800 series feature set but comes with a bit more performance under the hood to easily set it apart from the crowd. With some of the highest clock speedson the memory and GPU core at 765Mhz and 1125Mhz combined with Sapphires own Vapor-X cooling solution the Toxic HD 5850 is sure to offer some stellar performance numbers as well as excellent cooing performance. If the results from our testing of the 1Gb Toxic HD 5850 are any indication then this card from Sapphire should deliver the performance goods. The question is how good will it get?
