If the money is no issue, you can certainly go for i7 5960X, but since this CPU is extremely expensive and usually an overkill for home rendering purposes, I would advise to go for i7 5820K, which should serve you great as well for a lot less.
As for the video card, I would suggest you to take a look at NVidia's Quadro series, they are much more geared towards professional work (likewise, much less so for gaming). Depending on your needs, it might be worth it. QUadros have way better optimized drivers for professional apps, so you can expect a boost in performance even with their base models.
