Even setting aside the humorous cost level, how does it connect? o.o I certainly wouldn’t want my graphics card running over USB, but I’m having a hard time thinking of what other ports my laptop even HAS to accept input from an external device.
Two of the models in Enright3’s link seem to use Thunderbolt 3 connections which can reach up to 40 Gbps (HDMI is 10 Gbps).
You would need a fairly recent laptop to have the right connections, but as long as the laptop is built to handle it, bandwidth shouldn’t be a problem anymore.
Just saw this on Linus. the new Dell Inspiron gaming laptops starting at $800.
