If you are building a system from scratch, do not go with an A10. Go with i5 4590 with an R9 290. It would be a far better combo. I play WoW, and I have no issues at all with my main rig.
none of those, you need a r7 240 or a r7 250, just get the best GPU u can afford, the dual graphics of the APU is not recommended
Why is it not recommended? It plays quite few games really well by itself is there something about the apu I should know?
you get a lot of stuttering, it has improved from the past but its still there, if you are building a new computer get an intel i5 CPU and the best GPU u can afford, if its just for world of warcraft you can build something cheaper and it will run it maxed out
