Same as me,well i play the game ultra-high(depends on the weather cause my case is atx) on ultra txaa 4x 1440x900 am gettin 45-80 fps avg 56 high msaa 2x-4x 50-110 but 1440x900 is way lower than 1 1080p,still 770 is a high end gpu but watch dogs is an unoptimized game which also need a i7 cpu for ultra so for 1080p i'd say medium-high smaa
