FWIW, I'm still running an AMD X4 Phenom desktop with stellar performance paired with a decent OS SSD and proper video card. Provided no gaming or hardcore intense graphics. AutoCAD 2015 Revit has no issues with reasonable video. Latest version 2017 runs ok... it's a little glitchy with older video card.
Updated the video card twice since 2010 with no change to any other system variables. For basic home desktop it's been great. There's another comp for more serious computing...
