January 31, 20179 yr I'm looking at upgrading my server and cannot decide between these 2 CPUs: https://www.scan.co.uk/products/intel-xeon-e5-2609-v4-s-2011-3-broadwell-ep-8-core-17ghz-20mb-40-lane-64gt-s-qpi-85w-retail https://www.scan.co.uk/products/intel-xeon-e5-2620-v4-s-2011-3-broadwell-ep-8-core-21ghz-3ghz-turbo-20mb-40-lane-80gt-s-qpi-85w-reta There's ~£100 difference and the main difference is that the 1st CPU is 8 single threaded cores whereas the 2nd CPU is 8 dual threaded cores. I really want to create virtual machines on my unraid box so am wondering is it worth me paying the extra for the "better" CPU? Will the extra threads make a difference from a virtualisation point of view or will it just complicate things? Many thanks
January 31, 20179 yr Get the one with HT, it only complicates VMs in the sense that you need to pair physical core with HT cores for best performance. Also... are you really buying new instead of an eBay server pull for a fraction of the price?

February 1, 20179 yr I would avoid the QS and ES versions, and find a seller that offers 30 days of returns. But you can save a ton if you ebay.

I got four E5-2670v1 for about $70 each. So yeah... huge savings to be had.
