Hey all,
Daisy Chaining is not recommended. It will put a load on the Thunderbolt 3 connection and bog it down. So if you'd like to connect 2, then connect them both directly to the computer.
As for how much additional benefit you'll get by having two connected, it really depends on your software application.
Performance can be greatly improved in DaVinci Resolve Studio by connecting multiple Blackmagic eGPUs, however it’s recommended that you don't daisy chain the Blackmagic eGPUs to each other, but connect each Blackmagic eGPU to the computer directly with its own independent Thunderbolt 3 connection. Typically, games will only use just the one Blackmagic eGPU at a time.
Most of the above is taken from the FAQ for the eGPU.
