But then, the biggest problem is the lack of Sony first party games. But if you compine a high-end PC with a PS4 and a Nintendo console, you really don't need much more.
Well, personally I need everything. That's why I own a PC, PS4, PSV, XOne, WiiU, and 3DS. I need to play everything.
But if I was forced to choose, I'd leave the PS4 out. Its library is largely redundant when a PC is introduced into the equation, and its first-party software is hit or miss.
