Still how can he claim that PS4 is 80% of a Mac Pro GPU ?!
Specially since both GPU's are aimed at different tasks and I doubt drivers for D*00 will be optimised for gaming.
Also, he OP asked if the iMac was good for gaming... not should I buy a iMac or a PS4 for gaming...
My 2cents, I have a iMac with 780m and this are my max/min/average frames on Battlefield 4 with everything on max except AA which is off.

(was just playing when you replied
)
And this is on native resolution.
You can either reduce resulution to 1080p or reduce one or two sliders to High instead of Ultra. Or disable AA post processing completely and I think you get close to 60 average.
This is multiplayer btw.
