The Call of Duty: Ghosts requirements have appeared on Geforce, and a few things stand out. First, the game requires 6 GB of RAM. Second, it is a 50 GB file. And finally, Nvidia recommends a GTX 780 to run it, which is a $700 (£435) graphics card.
These requirements are higher than Battlefield 4, and it is generally accepted that Battlefield 3 looks much better than any of the recent Call of Duty games.
