Besides gaming and a GPU upgrade, this is the biggest upgrade you can make for your computer. It'll feel faster and more responsive in every way except framerate. I enjoy the 500GB size as it is large enough to use as a boot drive and to store almost all of my games and applications without having to worry about space constantly.
