I'm looking to build a new gaming PC that will last a while. I want to use a PCI-E x8 SSD + GTX 780 SLI in this build.
Now i'm looking around on the web to see what i need to support this in terms of motherboard and CPU.
My first setup was:
- CPU - i7-5820K (Support PCIe 3.0, with 28 lanes)
- Motherboard - ASRock X99 Extreme4 (Support for 36 lanes, with a 28 lane cpu the slots will be 16x-8x-4x)
So here i would think that my setup with a pci-e x8 ssd won't work cause the third slot is only pci-e x4.
second setup:
- CPU - i7-5930K (Support PCIe 3.0, with 40 lanes)
- Motherboard - ASRock X99 Extreme6 (Support for 40 lanes, with a 40 lane cpu the slots will be 16x-16x-8x)
here i would think this is ok with the pci-e x8 ssd. but it also much more expensive. and i read different things about how the the pci-e lanes work.
so please can someone help me out here and tell me how this pci-e lane stuff really works and if im right in my setups.
-EDIT- Thanks for all the comments guys, really helped me understand how things work a bit. and i think i have made up my mind in terms of what to buy for now. thanks!
It would work it just would be limited to x4 speeds. It sounds like you want the better hardware. – Ramhound – 2015-05-11T14:38:44.837
With a PCIe SSD, you appear to be placing the emphasis on disk speed rather than graphics power. For a gaming PC, this is not the usual way to go. However, even the new Intel 750 SSD "only" uses four PCIe lanes - what is the eight-lane PCIe device that you are considering? – Andrew Morton – 2015-05-11T15:00:06.910
Indeed the emphasis on speed for a gaming pc is somewhat strange but i want to see what this baby can do :) Mushkin Scorpion Deluxe, 240 GB PCIe SSD – Bram ten Cate – 2015-05-11T17:37:15.220
By the way: Instead of buying a needlessly fast PCIe SSD with only 240 GiB, get a 500 GiB or even 1 TiB SATA SSD. SSDs main improvement over HDDs is fast random access. You also get this with regular SATA SSDs. – Daniel B – 2015-05-11T18:10:19.643
Please note that the Mushkin drive uses PCIe 2.0, if that makes any difference. – Andrew Morton – 2015-05-11T18:50:30.160
