techPowerUp posted a review on the Sapphire HD3870 Atomic Edition
Sapphire's new HD 3870 Atomic Edition is a special version of the Radeon HD 3870 with a single slot cooler. This is only possible because Sapphire uses a new cooling technology called Vapor-X cooling that improves cooling performance considerably while keeping noise down. Another plus of this card is that it comes overclocked out of the box with full warranty.Sapphire HD3870 Atomic Edition Review
