It's definitely possible to see more than 2
I have 3 and can use all of them
And can actually add 2 more because the motherboard has a dimm.2 module
So a total of 5 of them
Though yes bifurcation would put my gpu at x8 not x16
But there's no real life issues with it at x8 anyway
Only 8 lanes available may be a limitation of your particular set up
There's cpu lanes and also chipset lanes
It does make reading your motherboard manual a lot more necessary
If you want to start using more than 1 nvme drive though
Yes, there are other configurations possible if you have the right hardware. I was meaning for the Hyper X card in particular, that you'd have to forgo the GPU to have any more than 8 lanes available to the card itself as the full setup needs 16 lanes which is the maximum the CPU gives the PCI slots.
As far as I know the standard setup is 16 lanes total from the PCI slots to the CPU - using both physical 16x slots will automatically split both to 8x (as you say, 8x is fine even for the current generation GPU's) which gives you 8 for the NVMe drives on the Hyper card, which is 4 each.
There are 4 other lanes dedicated to the closest M2 socket, which will be your OS drive normally, and then the final 4 for the chipset. This will handle all other devices including the DIMM.2 and other drives/sata connections with it's own number of lanes (28 on the latest Intel chipset) which will change the speeds they an run at.
The final total is 24 lanes to the CPU, which is the same on AMD and Intel unless you go to the high end like Threadripper.
I think we're saying the same things, just in a different way...
