Worse case scenario, dropping from a x16 PCIe 3.0 connection for the graphics card to a x8 has an essentially nil impact on performance, even if you were to use some of the CPU PCIe lanes for the NVME ssd. You will probably hurt the performance a hair by using some of the chipset PCIe lanes rather than the CPU PCIe lanes, but again you'd need to be running benchmarking software to even detect the difference.
Basically you're worrying about nothing.
Frankly though I remain unconvinced that > 4 cores (and hyperthreading at all) are of any significant use, outside of highly threaded applications.
