I remember playing Black Ops 2 Zombies with three other friends on the PS3 and it ran like 6FPS due to the lack of processing power and the amount of zombies and gunfire that was happening..
PS3 > Xbox 360, Newer hardware etc. I'll always be PC though. IF you want to just play games with no stress and stuff, get a console. I think PC gaming is a lot more stressful due to configuration and stuff. Might just be though.
