My old i7 is aging now, and it was overheating, and it was purchased back in 2012 and it uses the now superseded ddr3. I am looking at buying a new PC. I am considering getting either a Ryzen 9 or Ryzen 7 then getting a low to mid range graphics card and upgrading the graphics card later. My initial thought was to get a Ryzen 9 for a bit of future proofing but somebody told me that there is not that much difference between a Ryzen 7 and a Ryzen 9.. thoughts
