From: Dark_Spiret | #007if the specs are right then the ps4's graphics will probably be that of a gtx 660(non ti) which should be able to do current multiplat games at that res around 60fps. the more hardcore games however like crysis 3 or planetside 2 might be more of an issue without heavy optimization.
Dude, I run PS2 with a GTX480/i5 @ 1080p and don't drop below 50PFS even in big fights. I'm regularly over 90FPS in that game.
Crysis 3, I have no idea, but it won't be difficult. Any trouble running that is less hardware and more poor optimization on AMD machines.
But yes, I think the next gen of consoles will be close to current era PC games. At the very least, the hardware in the next gen consoles
are comparable to machines that can run newer PC titles at max. And those are games not even optimized to run on standardized hardware.
