Right now playing BF3 running on high with some AA at around 60fps. I have not played much of the newer games yet but will soon like to play Watch/AC:U/BF4 I draw the line when I can't run a game at least at mid settings with some AA at least 35fps. So tell me do I need to upgrade ? Obviously 970 will blow the 660 away. But I would rather not spend the money if I don't have too. I've read some requirements for these newer games but they are kinda misleading sometimes. If you guys think I really have to upgrade do you see any potential bottlenecks in my specs ?
