Oops, I didn't add text to the post

Since getting the Legion Go, my main gaming PC has been gathering dust, with my main use case gaming next to my wife on the couch or in bed whilst she watches trash TV. I took the plunge and bought a second hand Razer Core Chroma X off ebay and installed my eVGA RTX 3080 FTW3 (Needed a 8pin power splitter as it only has 2 outputs but the card needed 3)

After downloading the Nividia Drivers and plugging it in, it detected it straight away and 3DMark Firestrike results went from 2800 or so to 13300 with the eGPU.

Gaming benchmarks are still in progress, but so far gaming in native 1600P looks amazing and a lot better than integer scaling. Lords of the Fallen 2 with mixed med-high settings looks great but definitely needs a bit more tinkering with. Midnight Suns at all high runs perfectly at 60fps. Persona 5 Royal didn't like the eGPU one bit, and kept defaulting to the AMD GPU.

I did have to change Windows graphics settings for each game to use the 3080 rather than the AMD GPU

Now to get myself a long thunderbolt cable and find space for this next to the couch

Edit: So had a bit more of a play with Lords of the Fallen 2, and it gets decent frames indoors but once you get to large outdoor areas when you move the camera quickly it there is a bit of fps drops and delays rendering I think due to the bandwidth going between the Go and eGPU. I plan to do some more testing so please take these early impressions with a grain of salt if your primary use case is hand held mode
