ik, I built this pc with the things I had in my attic lol, it actually works pretty well, I can play gtav, xenoverse, and other games, it's a bit laggy, but yeah, I think that it's time to upgrade the ram if you say so.
I remember trying to upgrade mine from 8 to 32 let's just say somehow someway mistakes were made and I did not realize until it was too late. I wish you good luck that you dog screw up like me.
