I have some PCIe questions obviously, and please don't tear me apart, I'm not as versed in motherboard tech as many of you.
(What I'm running)
Crosshair vii hero
Ryzen 2700x
msi 2080 ventus
2xSamsung evo plus 970 1tb
4x(older)850/840 evo 256GB drives in raid 0 (these were salvaged out of my old Fx9590 pc when I built this one so I thought it to be better than discarding them)
32gb Vengeance 2666mhz
So obviously, I've used both m.2 slots in the board already (I do know one has it's own 4x lane to the cpu and the other is stealing 4x lane off the PCI16 slot). I know this drops me down to 8x pcie on my graphics card. My first question is: am I impacting my 2080 ventus running at 8x pcie vs running it at 16x pcie? My second question will pertain if the graphics card is fine at 8x pcie: If I use the ASUS hyper pcie board on the second pci16 slot and do an NVME m.2 raid 0 with 4 additional NVME m.2 drives to upgrade from my older ssd drives, is this going to interfere with the existing m.2 that shares this second 8xpcie lane ? (Or maybe there's an even better solution I haven't even discovered)
I'm already somewhat confused with the limited information I can find, and I'm not even sure if the PCIe Lane distribution images I've googled are entirely accurate, and no I won't be upgrading to new x570 and Ryzen 3000 series until at least early 2020.
(On a side note: I'm also confused why Samsung Magician will benchmark my 970 evo plus drives at 3500mb/s read and 3300mb/s write but userbenchmark will show only 2300mb/s and 2100mb/s, or is this just more evidence of why userbenchmark is a pos?)
