Intel Core i9-7980XE

Ignoring price, 18-core processor is a showstopper. Single- and multi- core performance is staggering and there's even more potential in overclocking. It's by far the king of CPUs.

Exceptional performance; Single-core results are incredible; Mature chipset and platform

Price; price; price; Monstrous overclocking power draw; Still no soldering between dies and heatsink

I'm coming from a 2009 2.66GHz 4-core Mac Pro. I'm no longer a fan of what Apple offers, especially in terms of price to performance and lack of user upgradable components. So after 20+ years with the Mac, I took a leap of faith and built my own PC.
