Depends what you are doing and whether the upgrade justifies the cost and productivity gain. I just bought several i5 quad core 3.2Ghz Dell Optiplex 3010 for our church for $35 ea. They run Windows 10 and LibreOffice just fine on a HDD. Now, if I'm crunching for distributed computing, I might want that quad XEON 24-core 1U server off eBay instead. Just depends on your workload and use case.
