I think the short answer is: It depends if you need the extra RAM or not. If you have a particular chore for your computer, and your computer won't do it effeciently now because of lack of RAM, then put in the new RAM because your computer will then do what you want it to do.
If, on the other hand, you want to add more RAM just for sake of having more RAM, well, that is up to you and your ego.
The best thing to do is to put the new RAM in and see for yourself. My guess is you won't tell the difference. But I could be wrong, because like I said it depends upon what you are asking your computer to do.
As a general rule, if your computer is lacking in the amount of RAM, then adding more RAM is the first thing to do to improve performance. The second most important thing to do is to get a fast speed of RAM. Third is go to Dual Channel.
Where your computer fits on that scale only you can answer, really.
