We've now seen a steady trickle of partner-designed Radeon HD 4890 graphics cards be unveiled since the launch of the GPU four weeks ago. Radeon HD 4890s ships at either 850MHz core and 3,900MHz memory (XT), or 900MHz core and 3,900MHz (OC) and are available for around £200 for the cheaper model and just a touch more for the OC.

Sapphire is readying its own HD 4890 that it hopes will steal the thunder from rivals. Encased in a Vapor-X heatsink and pre-overclocked, we've managed to snag a pre-production sample of the highest-clocked HD 4890 we've seen thus far. Read on to find out our initial thoughts.
