Probably, but it wont be pretty. The problem with dayz is that is requires a lot of CPU horsepower. 4GB of ram might not cut it either, when I play I regularly use 8+ GB (I have 24 total).
The fastest clock speed on your cpu is what you need.
Make sure to set the graphics to normal or high, never "low". Low forces the game to use the cpu for graphics rendering, making performance terrible. The 750ti is easily enough gpu to play the game on high as long as you have a fast cpu.
