I don't see it.
Probably even those PCs are better than Ps4/One just right now... in the end of the next generation they will be lacking power if you compare with consoles.
Just think about this... a 500/700$ PC of 2006/2007 can do what Xbox 360 or Ps3 is doing just right now? (Halo 4 or TLOU)
Obviously no...
So i recommend you to wait a little more.
PS: The Ram reserved to OS on PS4 it's not confirmed yet. (Some developers said it will be 2 GB)
