Nothing in computer technology is future proof... But it is descent CPU for budget builders. Go for motherboard with good brand like Asus or similar, with features you need. How many hd/ssd you need? How many usb ports etc. If you are going to overclock the processor, you good CPU cooler, like Nochtua or similar. Also good PSU like Antech, corsair, or Seasonic. Stable electric current is important when overclocking.
Intel would give you more speed, but it would also cost more, so a hard decision in there.
At this moment I personally would take Intel CPU and AMD GPU with Seasonic, or Antech PSU and Asus motherboard... But it would cost a quite a lot so my next upgrade is waiting for the release of DX12 and second generation of 20nm GPU... (even first generation is not out, so I have to vait at least too years. But I have good computer based on AMD Phenon 2 in my use with fast X210 ssd and it will be good enough at least two year from now.)
