Looks like a nice rig. One wonders, "If it is already built, why ask for advice?".
Except for long renders of Video codecs (transcoding) and effects, your build would handle almost anything else that I do. I would call it "a very thick client" , Like a supercharged ATOM/ION, on streoids. Shouldn't drag, at all, as long as you don't have extreme gaming or HD video expectations/aspirations.
