I'm trying to decide whether it's worth it to get a Samsung 990 pro PCIe 5.0 SSD considering it will steal lanes from my RTX 4090. I was told the following:
"The only way to get a Gen 5 SSD on a LGA 1700 CPU is to steal lanes from the GPU. In order to get a Gen 5 slot, it would have to bifurcate the PCIe slot the GPU is using, reducing it down to 8 lanes and using those 8 lanes to go to an M.2 slot.”
And there's a nice article that shows some differences in scaling performance here: https://www.techpowerup.com/review/nvidia-geforce-rtx-4090-pci-express-scaling/
tldr: While for old games the difference is pretty much negligible, for newer, modern DX 12 games you might lose 5-10 FPS if you bifurcate the PCIe 5.0 slot.
My current thinking is that it’s still going to be a while before PCIe 5.0 SSDs are useful in games because Direct Storage still hasn’t been implemented very much. As someone who is building a new computer only for gaming it would then seem more beneficial to just get a PCIe 4.0 SSD instead and avoid potentially losing FPS especially in newer titles.
Anyways, I'm just wondering what your thoughts are. Are there other considerations I should have? I'm just trying to fully weigh the pros and cons of either option.
