This is one of those questions that by asking you prove you don't have the knowledge to use the camera you're asking about. If you want to buy it and have the money to do so go for it - there, someone on the Internet justified it for you, go forth and enjoy your new camera.
The question might be answered with the 5d3 period in your mind only. Having two cameras each with complementary lens is a very nice option for shooting events. Have a 7d with it's implied reach is very useful for sports or wildlife. Your absolute 5d3 answer ( period ) is in your mind only.
