Years ago I bought a Razer Core, a Razer Blade Stealth, and a GTX 1080. For the most part, it was a dreamy setup - I would take my ultrabook to work all day and come home and dock it to unlock gaming capabilities, an ethernet connection, and an external monitor. But gaming was limited by the dual-core CPU of the Stealth and the GPU was limited to just 2 PCI-Express lanes.
In 2020, ultrabooks have quad-core CPUs, access to 4 PCI-Express lanes, and GPUs have become more powerful. Does an eGPU make sense in 2020?
