I am very happy with a Dell Precision 5510. I bought it as replacement for my MacBook Pro, maxed out late 2016, (MB) when it needs butterfly keyboard service (twice so far). It came with a Xeon processor and 32 GB RAM. for under 1000 USD. I run it with Ubuntu and compile software all day. My MB fans were blowing a lot and once even the battery swelled (service). My replacement Precision beats the MB in any aspect.
