I originally built my FSX pc from an old HP desktop which caused all sorts of problems, not least improving the power unit with the HP motherboard. Having succeeded I now want to up my CPU. If I change the motherboard and CPU, and add my old GPU , power unit etc.
..... can I then replace my old c drive (windows 7 os) and d drive (FSX and addons) to the set up and have the old scenery, PMDG 737 (most important!) working as before except from a better core?
