While we're still waiting for the 1GHz GPU clock-topping Radeon HD 4890 Atomic, Sapphire has presented a new RV790-powered card to make use of a Vapor-X cooler. Named simply Radeon HD 4890 Vapor-X, the card has a blue PCB and a dual-slot cooler (similar to that used on the Vapor-X Radeon HD 4870), 800 Stream Processors, a 256-bit memory interface and 1GB of GDDR5 memory, CrossFireX support and D-Sub, DVI, HDMI and DisplayPort outputs.

The upcoming card has stock frequencies - 850 MHz (GPU) and 3900 MHz (memory) and should become available in the next few weeks. A factory overclocked version is apparently also in the works.
