Hello clever_bug.
- you can use High-End GPUs, but they require higher bandwidth and a good CPU to work fine, that's why you can be disappointed about the performance expectations. The eGPU is made to improve your laptop performance, but if you spend to much in it, it could be more benefit to buy a gaming pc. What is your budget ?
- You can watch my second video, i have modified my desk to use an external screen :
- For the 3460, there is no other solution. You must remove the hinge because the cable is very rigid and you can't ply it at all. This was the most hard step of the installation, i had to remove the hing and cut a groove in the plastic to let the cable pass. If you find a better idea, do it ^^
- Yes, the GTX 750 Ti consumption is about 60W, but it's more interesting for me if i decide to change my GPU for a more powerful GPU and i didn't want to use a big ATX powersupply with cable everywhere ^^
