SSDs CAN help FPS in certain situations. for example, in the MMO Star Wars The Old Republic, the rendering request was being held on the read/write request (or something similar, i dont remember the details). once you switched to an SSD, those read/writes got much faster, and would no longer hold up the render request, therefore increasing fps. that is more of a symptom of poor programing id assume. in a game like dayz, which uses alot of streaming so we can play on such a large map, it will reduce stutters from HHD access, which will make the game smoother, and perhaps feel higher fps.
