I've found a cheap XEON E5-2699-V4 ES (22cores 44 threads) on ebay. I am looking a running a virtualised environment in virtual box running 2 domain controlers that also serve dhcp as well as nas, a web server, 2 windows 10 pro workstations and an Opensuse box. I also wanted to be able to play games on the xeon as well (not in virtual box). I have a few questions though before I buy it.
1. Is there any point in buying ecc ram (for the vbox network) I know there no point from a gaming perspective.
2. My copies of windows 2012 server is only licensed for 2 cpus. If I allow 4 threads in the server boxes does that count as 1 cpu or 4 for licensing purposes?
3. Will games run ok on a machine like this and if so how much will ecc ram affect the performance of the system?
4. Will a high end grapics card still run just as fast?
I'm no expert so any help would be appreciated.
