Still the required specifications left us scratching our heads a little bit. The need for a 64bit OS and 6GB of RAM seem more than a little weird. It is a given that most people that are going to play this game have more than 6GB of RAM and are likely running a 64bit version of Windows 7 or Windows 8, but we can only guess that these requirements are to help eliminate support headaches by adopting a standard platform bar for PC players.

Still Infinity Ward is recommending a rather powerful systems to power their latest COD title, but it is far more than the requirements that EA & DICE are set on for Battlefield 4 when it ships next week.
