Honestly, you'd spend $600-$650 to build a comparable computer. And that's not counting the fact that the PS4's software, both OS and games, are built for a single target. And that's assuming you'll get cheap peripherals and cheap case and stuff. And probably doesn't include the cost of a Windows license either. Specifically video cards don't start passing the PS4 until the $200 range, at least when comparing via syn…
Yeah, this is not true at all. You can get video cards that are better than the PS4's (by enough to counter any initial optimization, if not end-of-life optimization) for $150. Specifically, 7870 GHz editions.
Also, a $50 price difference doesn't invalidate my answer of $600-$650 --- in fact you'll notice that it lands exactly in my stated error range of $50.
EDIT: My bad, I found a super off-brand cheap bad-warranty version of the 7870 for $170.
But speaking from experience, don't buy a shit card from a shit company with a shit warranty.
