What would be the limiting factor if i tried to play this game on my pc? 

Processor: AMD Phenom X4 9550

Motherboard: Jetway HA07-ULTRA

Ram: 5gb mix and match miracle

Graphics: Nvidia gtx 550 ti

the ram followed by the gpu then the cpu

Arma 3 is a very intensive game with it's graphics as well as it's complicated AI, even the best computers won't have an easy task running the game.
