"If it aint broken, don't fix it" may be the simple answer to the question. Obviously if your having errors witht he cards it might be wise. If the cards are old and outdated, again might be wise. But if your just replaceing it for the sake of replacing it (havin a new one) there really is no point. For example I want a new Xbox Live headset. I dont however need one because the one I have isnt broken or outdated. I just want a new headset. S0 in my estimation, you probably wont see a difference so it's a waste of money.
