Currently my graphics card (Gigabyte 1080 Windforce) is in the 2nd PCIe slot, when I originally put the PC together, I checked the manual and it didn't state anywhere that there was a bandwith difference between the first and second PCIe slot and when I checked it again right now I still couldn't confirm that there was or wasn't a bandwidth difference, but I wanted to confirm that it won't be an issue. I'll be adding a NVME SSD(Seagate Barracude 510) and wanted to see if I needed to swap PCIE slots for the GPU. In the same vein, I'm worried about the SSD temps, since it will be right above the GPU and the GPU will exhaust hot air right onto it.
