First seen a month ago on the launch day of the Radeon HD 5800 series cards, Sapphire's HD 5870 Vapor-X model is finally closing in and should start to reach stores next week. The Cypress-powered card features 1600 Stream Processors, a 256-bit memory interface and 1GB of GDDR5 memory, DirectX 11 and CrossFireX support, and (of course) a dual-slot Vapor-X cooling system that makes use of vapor chamber technology and is claimed to be both quieter and more efficient than the reference cooler.
