CPU choice for Cubase 10.5, number of cores VS core speed

I read that Xeons are more reliable, stable, have better life span as they are designed for heavy duty. I read on gearslutz people comparing them with i7 and i9 with similar specs claiming that they were more efficient. I was thinking I could benefit from the extra cache memory they carry, and finally I can get a top of the line x99 mobo like Rampage V extreme (12x Sata, 10x USB3 on the back, 4 memory channels) for a fraction of the price of the new ones with similar features, that’s why I was considering giving it a try.
