I have an amd fx 4130 zambezi 3.8ghz quad core processer, g.snipe series 8gb ddr5 ram, a gigabyte mini atx motherboard, and a SAPPHIRE HD 6670 1GB GDDR5 Ultimate graphics card. Some games i run completely fine such as: WOW, Tera Online, EVE, Arma 2, firefall/etc. Then there's games like assassins creed black flag, an it just blows. It also gets crap compared to my brothers x51 gaming cpu when playing dayz, hes sitting at 60fps with a dual core, and my specs are higher but i get around 30, any solutions?

my tech teacher help me put this together.
