Probably not, if all you are going to render is V3 sitting in a comfortable chair reading a non-existant book.  If that is all you ever render, then stick to any version you already have; or switch to something else.

Some of us will actually do more than that scene you show and the reasons they give will help, if done correctly.  I can't say whether they are done right, but I also can't say they aren't.  I don't have the program yet.  Do you?
