MSI R9 390X Gaming 8 GB @ techPowerUp
 

MSI's Radeon R9 390X GAMING comes with a massive triple-slot dual-fan cooler, which turns off its fans completely when the card is idle. Thanks to the overclock out of the box, the card matches GTX 980 performance at 1440p at beyond. Like all R9 390X cards, the MSI R9 390X GAMING is equipped with 8 GB of video memory.
