Keep in mind also that they still need to optimize the game (no it's not fully optimized yet) and that better drivers need to be released from both nVidia and ATi for this game.
i7 3770k OC'ed @ 5.0GHz
SLI x2 EVGA GTX 780 ACX Superclocked @ 1200MHz / 6800MHz (custom OCTI vBios)
Ripjaws 16 gigs of RAM @ 1866
Samsung SSD 840 Pro
Everything watercooled.
I clearly have something that is goddamn overkill for this game, and should run it at 60 FPS locked at all time on Maximum Presets (doing it most of the time), but when I get in cities and some parts of the world it can drop as low as 30-35 FPS.
So yeah wait for better drivers, our rigss are not the culprits and we don't have bottlenecks, we just need better drivers / optimization.
