I've heard that COD 4 is demanding from a hardware perspective, so what are the best settings for optimal play? That is, where is the balance between good FPS and 'eye candy' (for lack of a better term)? My configuration is in my sig and COD 4 should be arriving today in the mail. Keep in mind that I'm a complete noob with gaming... this is my first game in over 5(ish) years. I'm really excited in a nerdy kind of way! Thanks for the help!
