the system specs have very little bearing on whether faster memory will provide a benefit - it's the software you are running that dictates whether faster memory will provide a speed increase
an example is modeling and lighting or video editing and photo retouching - if you do any of those adding faster memory will make all your effects complete faster because those tasks are memory dependent
