Call of Duty 4: Modern Warfare is a first-person shooter developed by Infinity Ward and published by Activision for Xbox 360, Playstation 3 and PC. It is the fourth installment in the Call of Duty video game series. It was announced on April 25, 2007 and was released on November 6, 2007 in North America. The single player game can be completed in well under seven hours, but the game engine and multiplayer are phenomenal.
At 1280×1024 the GTX 260 and the HD 4870 are neck and neck but when the resolution is bumped up the GTX 260 starts to pull away. The performance drop in the HD 4870 between 1280×1024 with and without anti-aliasing was most odd, though, but a repeatable result.
