Ok,so I need help. I want to play the Arma 2 DayZ Mod and I'm not sure if I can play it. My computer specs: Intel ® Pendium ® Dual CPU E2200 @ 2.20 GHz 2.20GHz,2GB RAM On 'Can I run it' it says it needs about 8-10 hard disk space. Have in mind I need both Arma 2 and Arma 2: Operation Arrowhead. I have some money to upgrade the computer as well. I know it's kinda shitty but I don't come from a rich family.
