Intel Core i5 7400/ i7 8700k with PCI-e 3.0 x16 graphics card and PCI-e m.2 Intel Optane SSD. Will it work?

[vinlupas9834]

I am looking at a computer that has an i5 7400. I am thinking of upgrading to an i7 [strike]8700k[/strike] 7700k. The computer has a GTX 1060 3GB, and I am considering upgrading it to a GTX 1070 or 1070 Ti, if I have the money. Both processors only have 16 PCI-e lanes max, according to Intel. Will it work if I add an Intel Optane SSD into the m.2 port, which uses 4 PCI-e lanes, into the computer with a graphics card that uses 16 lanes?

Edit: The computer already has a 256 GB SSD, and I wanted to use the Optane SSD as a boot drive because apparently it's faster than a normal SSD. Not cache for a hard drive that would still be trash anyways. I want to verify, how much of a difference will it make vs regular m.2 SSDs? And will it work?

You cannot upgrade an i5-7400 to an i7-8700K without replacing the motherboard also. The two CPUs use different chipsets and are not interchangeable on the same motherboard.

You can use both M.2 and a GPU. It depends on the motherboard and if the M.2 is on the PCIe bus or the SATA bus as to whether is will limit the lanes of the GPU. But even if your GPU was only using 8x PCIe lanes it would still do well. I think only a GTX 1080 Ti was slightly affected by the 8x lanes vs 16x lanes.

Just get a normal SSD, and skip the little 16GB/32GB Optane cache-drive junk, if that is the Optane being considered....
