Just so you know... Not all games will experience faster load times with an SSD. Newer games like Starcraft or Fallout 4 load at about the same speed as they did when I had them on a mechanical HDD. However, some of my OLDER games like Flatout seem to load a tiny bit faster.
Here his what you can do:
SSD
O/S, Browser, Media Players & Burners, Hardware Drivers, Office, Documents, Utilities
HDD
Downloads, Videos, Music, Photos, Installed Games, Misc. Programs, Backups
