It depends on a few things, what console are you on? PS3 or Xbox? Are you going to be streaming or recording videos for youtube or both? Do you want to play in HDMI or not. One thing you should know is that, if this is just for call of duty nothing else, you don't need anything over 720p because call of duty is only 640p, it upscales to 720 and can upscale to 1080p but doesn't look any better it looks the same or worse depending on the scaler in your monitor/tv.
