Sapphire Radeon R9 290 Vapor-X 4 GB @ techPowerUp
 

Sapphire's R9 290 Vapor-X comes highly overclocked out of the box, matching R9 290X in performance. The card's triple fan, triple slot cooler manages temperatures very well and offers a unique feature: you decide whether the card idles with one or three fans running, letting you focus on temperature or noise.
