MY friends don't believe me so I just wanted to prove it but I have an fx 4100 quad core and a gtx 670 2GB, if im playing battlefield 4 would my game be bottlenecked?
You need an fx8320 at least. BF4 would run really like a slideshow with that cpu and the gpu would be to powerful as well for the cpu to cope. Get an i5 4570 system and BF4 will play fine.
I'm not sure it would exactly be a slideshow. Unless you consider 45 fps a slideshow.
This article released today about Battlefield 4 Beta Performance should help shed some light. The benchmarks are for multiplayer. A link to the original Russian site that did the benchmarking is in the link below.
