Sapphire is AMD's larger board partner so as expected that have a pretty nice selection of AMD's 300 series graphics cards. Sitting at the top of the 300 series is the Radeon R9 390X. This is of course a rebrand of AMD's previous R9 290X, but with 8GB of GDDR5 memory. Also the rebrand has given AMD time to fine-tune the chip and add new features. This card is 100% DirectX 12 compliant and has AMD specific features like FreeSync, Super Virtual Resolution, and Eyefinity. Sapphire's take on the card brings with it their Tri-X cooling solution that uses Intelligent Fan Control II technology that will turn the fans off when the GPU is not running hot and a massive 10mm heatpipe to keep things cool, 16K hours capacitors to lengthen the lifespan of the card, a dual BIOS, and the card is of course factory overclocked. Let's jump in and see what this card can do!
