Re: Not bad
DELL precision 5510 about 1200 quid, 32GB RAM, 256GB SSD, can drive 2 4k external displays.
Supports USB-C external dock - so single USB-C cable provides, power/ network / displays / esata / usb.
Mine came with dell flavoured ubuntu (14.04).
I run VMs and C++ workloads and it's a decent mobile workstation, which replaced my 2013 MacTop.
If you get it, get the dock. and the 180 watt power supply as the laptop will require 130 watt of supply over and above the draw of the dock itself.
