Thanks everyone for responding. I just downloaded the demo for arma 2: operation arrowhead, just to see if i can run it, and it does, so does this mean i can run dayz as well? And the (future) stand alone game as well? I know i have to buy arma 2 and the expansion, i just want to know if i can run and play Dayz. Iam really interested in playing this, but before i buy i want to know if i can run it. Thanks for responding.
