Top end PC is always going to brute force things / pump out better, and few people are going to argue against that. The real story is a $400 box giving a mid to mid-high end rig a run for its money by effeciency. And what that means for development this gen on all platforms.
Every single generation since the original XBox has been the same thing when it comes to this. This gen is not suddenly going to be different. Give it a year or two, the expensive pcs of today will be besting the ps4. Exactly the same arguments are had as well. Its amusing.
