GamersNexus: "In this Watch Dogs PC video card & CPU benchmark, we look at the FPS of the GTX 780 Ti, 770, 750 Ti, R9 290X, R9 270X, R7 250X, and HD 7850; to determine whether Watch Dogs is bottlenecked on a CPU level, I also tested an i5-3570K CPU vs. a more modern i7-4770K CPU. The benchmark charts below give a good idea of what video cards are required to produce playable framerates at Ultra/Max, High, and Medium settings."
GamersNexus: "Watch_Dogs Creative Director Jonathan Morin recently tweeted that the requirements are as below; we'll analyze the Watch_Dogs minimum system requirements & recommended system specs, hopefully providing some insight as to why the game requires so much RAM."
