Honestly mate crossfire and bf4 isn't feeling very good ATM its obviously less smooth with a second card even though the fps is higher. I've seen this with 2x7950's and with my cousins crossfire 290x setup 1 card feels smoother with less frames in bf4.
I've seen this at resolutions above 1080p on both AMD and Intel based systems using latest drivers.
