Im not sure how good that graphics card is but im sure that the processor sucks. Dayz needs a good processor and even with a high end GPU, you will not get much fps if you would have that processor. And even if you would get a good processor, a decent graphics card would increase the FPS IF you have the good processor because good combination of the parts is going to increase the FPS alot and would prevent bottlenecking. In a nutshell, dayz is more processor dependent. Not a straight answer for you, but some information what you need to get dayz running good.
