I would say no.
Because the X99 chipset is more unpredictable than consumer models. It might only support ECC/RDIMM RAM, which is significantly pricier than standard non-ECC/UDIMM consumer RAM.
Additionally, the X99 chipset was launched in 2014, whereas the Z370 chipset came out in 2017. That’s a three-year gap, favoring the Z370. Generally, older motherboards have a higher risk of failure.
Regarding CPUs, there isn’t an i9-8900K available. The i9 series first appeared with the 9th generation (Coffee Lake Refresh), not the 8th generation (Coffee Lake).
For high-end options, you’ll find i7-8700K, i7-9700K, i9-9900K, and i9-9900KS.
So, based on what’s available, i7-8700K is the best fit.
It offers 6 cores/threads compared to i7-6950X’s 10 cores/20 threads, though overall performance is similar.
CPU power usage also differs: i7-6950X draws 140W, while i7-8700K uses 95W.
Clock speeds are 3 GHz base and 3.5 GHz boost for the former, versus 3.7 GHz base and 4.7 GHz boost for the latter.
Unless you require more cores/threads, i7-8700K remains superior. It’s newer, with a higher frequency, lower power consumption, and a more modern design than the X99.
