To make a PC (With OS) that is as strong as the PS4 would cost $600-$700, but would most likely make much of its money back from game sales and lack of having to pay for online.
However one could build a PC for $300 that while quite a bit weaker than the PS4, would still be a lot stronger than last-gen consoles and could keep up with games for the entirety of this generation.
Then again one could also build a PC for $1200 that is 4x as strong as the PS4!
My point is that PC gaming is whatever you want it to be. If you are poor and can only afford a $300 budget build + $5 games you will be happy as hell! But if you want to blow $2000 on a monster you can of course pay more for more.
P.S. Anyone who says these PC's would need to be replaced in 3 years doesn't understand that upgrading is optional, and a PC that is as strong as a PS4 will be as viable for gaming as long as a PS4 is. However you can upgrade IF YOU WANT TO. This is called FREEDOM!
