Surely the selection of games counts? Can you get Killzone Shadow Fail for the PC? If (exclusive) PS4 games are desirable, a 10x more powerful PC will be irrelevant.
One of the main reasons I purchased a PS4 is for the exclusive titles. I still use my PC for gaming. I can also say this, Fifa 14 on PS4 looks way better than on PC. Same goes for Assasin's creed.
Sure, a year down the line from now they will look similar, and a few years down, it will look way better on PC, which is the case with games at the moment.
It does not matter how good your PC is, if it is a bad port, it is a bad port.
The difficulty is getting a fair test because it's hard to know what the developers have done to get performance parity across the platforms.
True. It will be tricky.
