If I put my "Corsair Force Series MP600 NVMe PCIe Gen4 M.2 (1GB Cache) 1TB SSD (OS)", in Slot 1, will my GPU and/or M.2 be Bottleneck?

If I put my M.2 in slot 2, will my M.2 and/or Chipset be Bottleneck?

The top slot m.2 will have full bandwidth without impacting other devices. Same goes for the top PCIe slot, it has a direct connection to the cpu. All else will connect to the chipset which in turn connects to the cpu with 4 PCIe 4.0 lanes. So they are share the bandwith with eachother.

Adding to that, even if you do an indirect connection, the odds of you noticing it in real life are pretty small.
