All mobile workstations, regardless of vendor, are overpriced in comparison with gaming laptops, because those who buy mobile workstations are forced to buy them for a few features that are missing in gaming laptops.
As another poster has already written, a common strategy when buying a Dell Precision mobile workstation is to buy them with the minimum RAM of 4 GB and with the minimum SSD of 128 GB, with the intention to dump the original RAM and SSD and buy something like 64 GB of ECC RAM and a fast 2 TB SSD, at much lower prices than from Dell.
The only reason for the 4 GB RAM configuration is because Dell will not sell a laptop without RAM or without a SSD or HDD.
The economy from buying yourself the RAM can easily be up to one thousand USD or even more, even after paying for the mandatory 4 GB.
