I have a 2018 Macbook Pro with 4 USB-C ports. I also own 1 LG Ultrafine 22" 4K monitor and am debating on getting another. I use my computer for work as I work in marketing, but sometimes I'll play some games. I don't really play anything crazy, mostly just Cities: Skylines, Overwatch, and Skyrim. Right now I pay for Shadow.tech because the latency isn't that bad. But I somewhat notice it and I'm debating on just getting the Razer Core X and an AMD GPU. Problem is, the Razer Core X only has 1 Thunderbolt port. I know the LG Ultrafine only works with Thunderbolt. I have been reading posts on here and people have talked about getting the Sunix IT USB 3.0 adapter. How do you install that into a Razer Core X? If I'm not mistaken, the Razer Core X only has one slot for a GPU. 

I've also thought about just keeping the monitor plugged into the computer, but am I going to lose any performance on games? I don't run any crazy intensive programs (Photoshop, Illustrator, and XD are probably the most intensive). The eGPU would 100% be for games. Will plugging the monitor into the computer cause games to run like crap? I don't need 144hz here, hell 30 fps would be fine for these games.

 

Thanks!

You do loose some performance in games when the display is connected to the MacBook Pro instead of the GPU in the eGPU box. Search this forum for loopback or internal display.

The LG UltraFine 4K displays work with USB-C (they don't require Thunderbolt). The LG UltraFine 5K does require Thunderbolt for 5K.

For 4K60Hz USB-C displays like the LG UltraFine 4K, get a Huawei VR 2 cable. Search this forum for that.

@bick as you own the 1st gen Ultrafine 4K you are actually in luck... it uses USB C like both second gens are capable of. As the ever wise @joevt said, grab that cable and you'll be good.

Reg direct GPU connection, in Windows it doesnt matter so much as drivers are great but in macOS its terrible to the extent a lot of games are unplayable, get that cable and connect directly.

Oh that's awesome. So if I buy a fancy USB-C to Displayport cable that'll work? That's awesome! Thank you for your help.
