Thanks for the responses. Was aware it would do nothing for framerate, just curious about load times, read some stuff about it not being that significant an impact because of RAM and the like.
Anyway. If I just wanted to install Windows and games on it (I use my PC for nothing but games), should I prioritize capacity or speed? Any suggestion on capacity? I don't tend to bounce around games, I almost always start a game then play it till it concludes without touching another game, so maybe I could get away with a smaller capacity and just move games to it as I play them.
