Question/Opinions About My CPU Options

I am trying to save up to go with a Libreboot or Coreboot desktop and laptop down the road but in the mean time I have my Ryzen 5 2600X; an i7-6700; i5-4590; an FX-9590 and an FX-6100. Would it be the best idea, from a privacy and security standpoint, to go with the FX-9590 and FX-6100 over the i7; i5 and Ryzen 5 ? I would still be on a closed source BIOS but would be free of the PSP and ME and allow me to try to sell the rest to use towards the Libreboot systems. Thoughts ?
