Lost Planet 2
Version and / or Patch Used: Standalone Benchmark
Lost Planet 2 sees the Sapphire R9 280 Dual-X 3GB OC perform slightly above the R9 270X 2GB. At the lower resolutions, we see some great performance. Moving to 2560 x 1600, though, you can see we fall short of that 60 FPS average we're on the hunt for. The R9 280X 3GB, on the other hand, has no problem getting it.
Just Cause 2
Version and / or Patch Used: Latest Steam Update
Just Cause 2 numbers, while strong across the board giving us playable FPS at all resolutions, sees the Sapphire R9 280 Dual-X 3GB OC fall actually slightly behind its younger brother, the R9 270X 2GB, at the higher resolutions. Only at the lower resolution is it able to come out ahead.
