AMD R9 270X Review
Obviously if you're buying a midrange GPU you should run at midrange settings, so with the knowledge that we maintain the maximum possible image quality it's clear that the 270X isn't enough graphics card for Crysis 3. The GTX760 is 50% better and even the lowly GTX650Ti matches its mere 20FPS.
Far Cry 3
The gap between the GTX760 and the R9 270X tightens in Far Cry 3. Despite it only pushing around 30FPS, the pace of the game is such that it's smooth in all but the most explosive outpost battles, although moving up to 2560 taxes it too much.
