It does not cost 2k for a solid gaming pc, I built my last system for 4hun (true I get half price discounts on company related stuff but deals are out there) and it can do everything a ps4 or xbox one can do plus more- 2 years after build- no competition (plus I can upgrade for a fraction, consolers can't without buying a new entire system). The power is multiple times greater, the graphics are more advanced, and I don't have to follow Sony or MS rules and policies and their lack of usability and content restrictions.
Yes if you want to go with a far inferior system of PS4 or MS definitely go with PS4 but if you want the real deal holyfield you do it pc.

Here's proof from an industry expert
"NVIDIA spends 1.5 billion US dollars per year on research and development in graphics, every year, and in the course of a console's lifecycle we'll spend over 10 billion dollars into graphics research. Sony and Microsoft simply can't afford to spend that kind of money. They just don't have the investment capacity to match the PC guys; we can do it thanks to economy of scale, as we sell hundreds of millions of chips, year after year.........If you want to go faster, you need a more efficient design or a bigger power supply. The laws of physics dictate that the amount of performance you're going to get from graphics is a function of the efficiency of the architecture, and how much power budget you're willing to give it........you're not going to get anything that is significantly more power efficient in a console, as it's using the same core technology. Yet the consoles have power budgets of only 200 or 300 Watts, so they can put them in the living room, using small fans for cooling, yet run quietly and cool. And that's always going to be less capable than a PC, where we spend 250W just on the GPU. There's no way a 200W Xbox is going to beat a 1000W PC......The technology that we're applying to PC graphics is literally state of the art, at the limits of semiconductor technology. That's why I don’t think it’s possible any more to have a console that can outperform the PC."
