I have two of these workstations, a dell and a lenovo w520. My lenovo is from 6 yrs ago. 8 cores, 20gbs of ram. It's a beast. I figured I needed the power. The truth is that they both have been sitting in the same spot now unmoved for a year. One at work and another at home. Last time I traveled with one, I hated myself. I carry around a chromebook or a lightweight lenovo carbon if I need to carry things around. With 24/7 cheap internet. If I need power I can VPN to work/home/cloud.
