You might have a leg to stand on if you used the term "average PC" instead of "highest-end," but as it is you're out of your goddamned mind. You realize a single GeForce Titan has almost triple the graphics processing power of the PS4, right? You're making a huge assumption by saying two-thirds of that power is "wasted" on the system running Windows. I'd be interested to hear how you think it works out that way. And if you really want to go to extremes, you could have three of those in a single machine... I'd love to see the PS4 play Crysis 3 maxed out at 5760x1200 and 8X MSAA without issues.
Really, though, if what you're claiming could happen does, in fact, happen, it won't be because a PC can't "pull it off." It will be because the developers chose to do a shitty port.
