The first AMD Radeon R9 380 graphics cards with 2 GB and 4 GB are already published. But before we review the 3xx series graphics cards, we would like to evaluate again another inexpensive AMD Radeon R9 280 graphics card. To be more specific, we test the Sapphire R9 280 Dual-X OC 3 GB, compare it with the previously tested video cards and also overclock the Sapphire graphics card.
