Really depends on the expected usage. The new APU's look good for say, someone who plays facebook tier games and wants to run general media. Granted, they are faster then whats in a ps4/xbox one, so you may be able to get away with some MOBA stuff this time around as well, as well as hearthstone and the like.
Anythign more then that, if you want a better experience, you are going to need a dedicated GPU and CPU.
I'm looking at a ryzen rig myself, granted with a kid it's hard to find the cash. my 290x still chugs along fine with what I play. Doesn't help that the 580x series is so overpriced due to coin mining these days.
