Last year AMD released their new Radeon HD 5800 Series of graphics cards which quickly became a big success due to the numerous improvements made over previous generations. Over the course of the last months AMD has been adding more cards to their DirectX 11 lineup quickly, most recently the Radeon HD 5670.
AMD's Radeon HD 5770 has been out for several months as we are seeing the first customized designs now. Sapphire has chosen to stick with the proven AMD PCB design and added their custom Vapor-X cooling solution. Unfortunately the clock speeds have remained the same as on the reference design: 850 / 1200. Considering that all other overclocked version from other AIBs (that I have seen to far) go to like 875 / 1250, there is not much difference anyway.
Sapphire HD 5770 Vapor-X can be found online for around $175, which is $20 more than the reference design from AMD.
