I was wondering if Call of Duty would run smoothly on my rev A G5 Dual 2.0 stock. I'm not a heavy gamer, I just plan on playing once in awhile and I have no plans on upgrading the video card. Will Call of Duty run okay with 512MB of ram? What should I set the resolution at when I'm playing the game? I'll be using a 19" CRT monitor (Viewsonic P95f+). I've never played games on a Mac before so I'm not sure how things will be. I really hope I can play this game without upgrading anything. I have already spent a lot of money on the computer itself. Any help on this would be appreciated. Thanks.
