Nothing special, just follow the instruction, then download drivers from amd.com, 3-4 system reboots total - and that's it. Magic!

The idea of building this setup is to jump into UWQHD gaming. I use my laptop both for work and gaming. But its impossible to enjoyall the good of UWQHD 144hz monitor without GPU boost. I thought about changing laptop or buying gaming PC, but eGPU is simply cheaper and more flexible solution. And its cooler and smarter 😉 Now I'm happy! I can play Witcher 3 on Ultra (just turn off NvidiaHair)  with comfortable 45-50fps avg on 3440x1440. I can play Dota 2 with 90-110 fps. Or I can lower graphics settings and add  more smoothness. The bottleneck here is not a TB3 bandwdith, but CPU. If I go for silent profile, wich limits CPU freq on 2.0Ghz, the system suffer 30% fps loss! And gets 100% CPU load. So keep it in mind. The build is rather noisy if you use it effectively. And I cant blame eGPU or laptop only.

Hi! Very nice setup!

 

I have two questions, is your laptop marked as USB 3.0 or as Thunderbolt? At Dell's website, it says that Thunderbolt is optional.  I'm asking you because I found one at a reasonable price used, but the owner does not know if it is only USB 3.0 or thunderbolt. 

 

Second question, I see that you have a cooling base for the laptop, did it actually made it work cooler and thus, quietly? 

Thanks in advance.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
