The minimum system requirements for the PC version of Call of Duty Ghosts have been revealed by Infinity Ward, and they're pretty similar to those released by Nvidia earlier in the month.

For the most part the required specs aren't too demanding, but needing 6GB of memory and a 64-Bit OS is somewhat baffling.

Minimum System Requirements

CPU: Intel Core 2 Duo E8200 2.66 GHZ / AMD Phenom X3 8750 2.4 GHZ or better

Hard Disk Space: 40 GB

Sound: DirectX compatible sound card

For caparison here are the minimum system requirements for Battlefield 4.
