First Arma has been a more CPU intensive game rather than GPU. Next NVIDIA is better then AMD when it comes down to reliability and bang for your buck. AMD is cheaper but can get the job done NVIDIA is being more supported on games then AMD. Next let's go over CPUs INTEL beats AMD in quality and just being better. Don't get me wrong I run a AMD A6-6300 6 CORE. It's a work horse and gets the job done. AMD CPUs are good for overclocking your PC. AMDs have an awesome amount of cores which makes it good for it. But INTELs are faster and the best around. AMDs are by far way cheaper so you can get higher end ones for as cheap as an I5. I run an AMD A6 6300 FLfor my CPU and GPU I run a NVIDIA 760 2GB enthusiast edition. I get about 20 fps on Standard graphics and clouds off. If you want better FPS your gonna have to break out the old wallet it can't be fixed with your specs. Only replaced you'll have change alot depending on your PSU RAM MBOARD AND POSSIBLY RAM.
