Introduction
We've now seen a steady trickle of partner-designed Radeon HD 4890 graphics cards be unveiled since the launch of the GPU five 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 both models.
Sapphire has now unleashed a Radeon HD 4890 that it hopes will steal the thunder from rivals. Encased in a Vapor-X heatsink and pre-overclocked, the ATOMIC version of the card ships with a 1,000MHz core and 4,200MHz memory. The fastest HD 4890 of them all, does it provide good value at £250? We find out.
