You can't build something as strong as the ps4 for the price of the ps4, especially if you're factoring in OS. Building a PC for less than $800 is dumb IMO because you don't really start seeing large benefits over the PS4's power until around that price range. I'm not saying that you can't make a strong PC for 5 or 600, but I just don't think the increase in power is great enough to really make that much of a note of it.
