Hello, I'm still a little new to the Mac so need some help. The Call of Duty 4 app is on 50% off for a limited time and I am considering purchasing it. Some of the questions I had were: Will it run smoothly on my system? Please see sig. The only thing I upgraded was the RAM from 4GB to 8GB. Everything else is stock as sold by Apple I believe there is a new game coming out soon (Battlefield something). Will this be available on the Mac? Is it worth it? I don't plan to play more than 1-2 hours a week and will probably play for a long time from now. I'm sure you can tell I have no clue about these things... I'm quite past the age, you know. Thanks!
