Optimal choice would be an I7 4960x or other 6 core intels. After that, I7 4790k, which you might oc for further performance. After that, an I7 4790 or a xeon 1231v3 (essentially the same, just no iGPU). All these are a good bit stronger than I5/8350. An overclocked I5 4690k *almost* holds up to an overclocked 8350 in rendering but beats it everywhere else not heavily threaded.
So afterall, it depends on your budget. lf you have a lot of money, go with the 4960x. If you have enough money, go with the I7/xeon. If you are on a budget: do you only 3D render or do heavily threaded tasks? Go with the 8350. If you render a little but also game a bit, I5 is your choice.
As for the GPU, I'm not familiar with blender, but I don't think the...
