Yes, if you are a creative professional and have to deal with heavy multitasking, adding a second screen to your system can help you do more tasks at the same time. It can be fun like you are watching a movie on a full screen and designing graphics on the other screen. But, if you are an average person who has to deal with daily office tasks, you should probably avoid adding a second screen since this will cost you more money. So make sure you know why you need a second screen.
