Performance dilemma

[Dagon]

Option A
- PCIE4 M.2 NVME in slot connected to CPU
- GPU (4090) runs at x8

Option B
- PCIE4 M.2 NVME in slot connected to chipset
- GPU (4090) runs at x16

Which would give the best performance? I know dropping the GPU to x8 loses 1-2% but not sure about difference between CPU/chipset for the M.2

Yeah I think Option B is probably the way to go, thanks.
