The GPU on that is inside the CPU (it's an AMD APU) so the perfomance would be weak in the graphics area. I would suggest getting one with a discrete GPU. AMD 7800 series + or Nvidia GTX 560 or higher.
I'd say drop the offhand axe and get another sword instead. In my eyes the axe doesn't offer you much in this build (replace sharpened Axes).
You shouldn't need unsuspecting foe as you don't even have a stun and take rending strikes or deep cuts. Overall offhand sword over axe gives you: Ranged strong bleed, a block+bleed and profits from blademaster which you have taken already.
it's too single target for PvE, I run with sword/axe and I run in and use whirling axe then flurry straight after (using signet of rage passive) and usually by that time only a few more whacks are needed to kill the goon. Plus I take "on my mark" for veterans/single guys
