Going to be upgrading from a budget Intel build to a better, AMD build over Christmas. Upgrading my CPU and MoBo, using old GPU, PSU, SSD, HDD, and RAM. Also going to be switching from Win 7 to Win 10. Right now Windows and most of my games and files are on my SSD, some on my HDD. I need to keep all my files and games (would take weeks to re download with my wifi), but I've only ever done fresh installs of windows from media. Not sure how to proceed...
