MSI Radeon R9 280X Gaming 6 GB @ techPowerUp
 

MSI's Radeon R9 280X Gaming 6 GB comes with twice the video memory of the reference design. We will test multiple resolutions including EyeFinity and 4K to see whether it really makes a difference. Another highlight of the card is that it's really quiet, quieter than any other R9 280X we've tested before.
