New PC

looking at the specs, you obviously have money to spend. Therefore I would not recommend what the other guy said as AMD is only competitive at pricing, not performance. If your motherboard has a m.2 port, you should get a ssd for that and remove the sata3 one. normally I wouldn't recommend 32gb of ram, but you said you were doing rendering and it looks like you have the budget, so go for it and about ddr4, yeah, there isn't much benefit in performance, but again, if you want to spend the money, go for it. If you are worried about playing disco, don't be. I have decade old Toshiba Tegras running it fine. Rendering, however takes processing power and ram.
TL;DR: If you have the money and are passionate about it, more power too you and replace the ssd with an m.2 one. If you need to mortgage your house over it or cut some meals, don't.
