HP z8 single cpu vs HP z840 dual cpu

hello
I'm Looking for info regarding best setup for DavinciResolve
in the new reference for #15
the new Z8 with dual gold 6132
Its too expensive for me
I thought to buy it with one CPU and in the future add another if I would need it
in your experience is it a wise decision?
is it wiser to buy an old Z840 with 2 CPU instead?
thanks
Junun
