PhantomShuriken

I posted this asking for help. Can someone please help me? This is the only place I can come to to get help with fellow Arma players.

1920x1080 AMD A6-3620 APU @2.2 Quad-Core (I have overclocked with AMD app to 4.0ghz) nVidia GTX660 Ti Overclocked by EVGA 8GB RAM I get around 15-20fps in any resolution and even in any setting. Game is only stablish in other games outside of Wasteland. I need to know if the AMD A8-3xxx series for the FM1 socket (either the 2.9ghz or the 3ghz black edition) will give me better performance or if something is wrong. I just really want to play the game because it is amazing!
