Realistically no. In the case that a game is loading information from the storage medium at the start of a level, the second or two of low FPS while data is loaded will be shorter. Other than that there isn't anything to see FPS wise. Having an SSD won't increase your max FPS or change your average really. It has potential to raise your minimum if that minimum occurred at a point where data was loaded, but that is a split second instance typically even with HDDs.
