Not sure why this is downvoted. Almost all (if not all?) consumer motherboards will drop the 2 x16 slots to x8 mode if you insert anything in the second slot. So using a PCIe riser for NVME SSDs means your GPU will get less bandwidth. This may or may not be noticeable, if you are running PCIe 4 the x8 will definitely not bottleneck the GPU, but x8 PICe 3 lanes probably will, especially for cards with less VRAM.
