I need to replace AMD processor and MB with Z170 and 6700K (I hope). OS is OEM Win 10 upgraded from 8 to 8.1 to 10. Machine is used for business and flight simulator. OS, tax preparation software, Quickbooks, MS Office, client data all on a 1TB HDD. Simulator is on almost full 500GB SSD. Rebuilding tax files on HDD and P3D files on SSD will be a major headache (read days and days). Suggestions, advice, references, and outright solutions are solicited (short of suicide or whole new machine).
