Sapphire R9 290X Tri-X OC 4 GB @ techPowerUp
 

Sapphire's custom design R9 290X Tri-X OC impresses with low noise levels, that still run the card at cool temperatures. The card is also overclocked out of the box, which makes it run faster than GTX Titan. In Europe, the price over reference is just 10%, which makes the choice a no-brainer.
