I am trying to build my first gaming PC. I want to get an ssd for my OS and games like BF3 and Skyrim. I am gonna get a 1tb hdd for the other random stuff like music and pictures. I was wondering, how do I choose what files are on what? If I were to download Skyrim can I choose for it to be on the SSD? Or will it fill the ssd and start going on the hdd?
