im asking because i tried to play BF4 with supersampling at 200 % and i got very low frames...maybe they need to release an update?
BF4 is extremely taxing on a PC. And yes, they do have some optimisation issues that need to be fixed, some of which have already been worked on. I'd say wait until next-gen rolls around and if you don't think your CPU is performing well enough, then upgrade at that point. There's no point upgrading now and feeling buyer's remorse when your current cpu could have been enough.
