Results: Arma 3
Arma 3 appears either CPU- or memory-bound at our standard quality settings, using resolutions up to 1920x1080. Yet, there are problems with both hypotheses. First, the $1600 and $2400 systems have the same CPU, but achieve vastly different frame rates. Second, the $750 PC pushes more memory bandwidth than the $1600 baseline, and both generate similar frame rates.
My $2400 effort barely outpaces Don's $1600 competition at medium resolutions and Arma 3’s Ultra quality preset. But it establishes a more significant lead at 4800x900 and 5760x1080. The $750 setup easily surpasses its 1920x1080 target, but struggles to offer playability at higher resolutions using the same settings.
