NVIDIA GT610 ummm yeah... minecraft it can play easily and garys mod easily since they have like zero requirements. but dayz standalone will likely be on lowest possible settings. you will either have to spend $800+ buying a prebuilt to play on high settings at 1920x1080 at good fps, or you need to assemble your own for $400.
Medium settings or 1080p (or is it 1080i) will be a good number for this on most games it would seem.
