I am trying to save up to go with a Libreboot 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 ?

I have given thought recently to getting a Pixel 5 in a few months and putting Graphene OS on it. I have a Pinephone CE that I am waiting for things to mature and use a Teracube 2E that has /E/ OS on it. I already only use open source, non Google, apps. Would it be a waste of resources to go for the Pixel 5 being that it has no removable battery unlike my other phones and would instantly be on a limited life span ? I'm already off Android so my privacy and security are already in a pretty good state although it can always be better but it seems I have to succumb to buying a new device every few years to get that which I detest being forced to do. Just looking for opinions to supplement my own.
