VM Host - Looking for advice on CPU Alternative

[GoblinKiller]

Hello,

 

Hoping someone could provide some guidance.

 

I have been running a workstation with following specs:

 

Motherboard: Asus Z10pe-D16 WS

RAM: 128GB DDR4 ECC

CPU: 2x Xeon E5-2620 V4

GPU: Asus Strix 1070

OS: Windows 10 Pro

VM Software: VMware Workstation 15 Pro

 

The machine is mainly used for running several VM's for basic office and web browsing purposes anything between 15-20ish machines at a time however my CPU generally tends to be running to max these days and was looking at upgrading the CPU's now and this is where I need to advice.

 

saying within the V4 variants of the E5's drives the price up very quickly if you look at upgrading to at min a 12c/24t option but if looking at some within the V3 variants the price is at times way less than half (both v3 & v4 I look at are second hand).

 

What i would like to know is how big a performance impact will dropping to the V3's have versus staying within the V4 is the massive price jump worth it?

 

Any insight would be greatly appreciated.

 

Cheers
