Bought myself a Razer Core X (Thunderbolt 3 eGPU enclosure) for CAD$109.99 a few days ago. Was a discount of 71% off from an original price of CAD$389.99. Not sure if the US site reflects the same kinds of savings. https://www.razer.com/ca-en/gaming-egpus/Razer-Core-X/RC21-0...
E: Thanks for all the replies. I have a XPS 15 that was, maybe 5 years ago occasionally reliable for playing Doom 2014 at 1080p for half an hour before the gpu would shut itself down, maybe I could have benefited from one of these + a desktop GPU...
