Sapphire R9 285 Dual-X OC

The crew at ThinkComputers had a ot of nice stuff to say about the Sapphire R9 285 Dual-X OC they just reviewed. AMD recently announced their Radeon R9 285 graphics card, this was their first major graphics card announcement since the R9 295X2 back in April. Looking at the naming of the card we expect it to be a replacement for the R9 280, but is it really? It has the same number of shaders, TMUs, and ROPs as the R9 280, but has a narrower memory bus at 256bit (vs 364bit of R9 280X) and less VRAM (2 GB vs 3 GB), although that memory is clocked higher (5.5 GHz vs 5.0 GHz).
