Hello,

I was recently tipped to the idea of using an external GPU on an older laptop as a way to "upgrade" the system.

https://egpu.io/

However, I see laptops generally have only a 1x mPCIe slot. The web site recommends using a 1x to 16X PCIe adapter to allow the use of a discrete video card (or similar.)

Brings me to my questions:

1 - Has anyone here actually done this?

2 - Is the video hampered by the PCIe bottle neck?

Thanks,
Michael

The best option is to have a desktop computer as most desktop computer have PCI-E x16 (2.0 or 3.0)

A few newer laptops have Thunderbolt 3 which is better then PCI-E x1 (2.0 or 1.1) and can work for OBS-studio.

Beware, some laptops have a BIOS wireless slot white list lockout that that only allows a few PCI-E cards to work in mPCI-E slot. For those system, the BIOS will probably incorrectly think a graphics card, or whatever it is in mPCI-e, is a wireless card and lock out system. https://www.google.com/search?q=laptop+unsupported+wireless+card
