I’m trying to assess whether or not to try and run a second GPU in my second full length slot. My mobo manual reports the fatest the second slot can go is pci-e 2.0 at x4 lanes. A paltry 2GB/s correct?
Can anyone comment from personal experience?

For exllama not much, for others a bit. On llama.cpp I lose 10% by halving the bandwidth.
depends on the board, seek the manual, rtfm :D
and if turboderp is right, it largely doenst matter.
