Crysis 3 needs 8GB RAM for playing at maximum settings: http://www.crysis.com/us/pcAccualy Crysis is pretty dope on RAM and Call Of Duty Ghosts are the only two I can think of, ED is not one of them though. And that is a good thing, because the reasoning behind the other two games is rather stupid..they did it on purpose to be future proof?
yea...
COD Ghosts doesn't use much RAM: http://www.vg247.com/2013/11/04/cal...maximum-settings-users-create-mp-fov-unlocker
Battlefield 4 needs lots of RAM due to a memory leak: http://www.reddit.com/r/battlefield_4/comments/2fng3j/battlefield_4_memory_leak/
I'd recommend anyone getting a gaming PC to have 8GB so they can play all games available, but 4GB is suitable for 95% of games out there currently. This situation will change over the next few years with PS4 & XB1 having 8GB RAM, thereby pushing PC gamers to follow suit. Not withstanding shoddy ports of course! *shakes fist at Ubisoft*
