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.
