I want to upgrade my system to an i911900k and appropriate motherboard, I require the following components to be connected,
• X1 NVME (Samsung 970 Evo)
• X1 3090FE
• X1 NIC (x540)
4 lanes for the NVME
16 for the GPU
4 or 8 (not 100% sure) for the NIC
[Edits]
What kinda mainboard [size / spec], are you looking to use?
The i9s PCIe bank, will accommodate for an 4.0 NVMe + a x16 lane [aka, the GPU]
At a minimum, a 540 NIC unless I’m confirmed wrong, would need a x8 lane to run
The i9-11900k only has 20 available. Unfortunately while you have the bandwidth to run the network card because its only PCIe 2.1 it will not be able to use the full bandwidth of the 4.0 PCIe on the CPU.
11900k has 20 PCIE 4 lanes.
Look at the motherboard layout to see what you get.
With the Z590 AORUS Elite for exemple
You get 16 lanes for the graphic and 4 lanes for the nvme drive. (PCIE4)
The rest of the pcie slot run as pcie3
Look at the transfer speed.
PCIE4x8 = PCIE3x16…
So you can run basicaly any GC in a PCIE4x8 without noticing frame drop.
May be not with the 3090.
But my point is that with your NIC you need to check if PCIE3 would be enough.
I think so.
Always and never, there will always be new gear out in a month, 6 months, next year that is better than what you can get today, so really it depends on what you need.
If you NEED a new system today, its not worth waiting. If you have a last gen top end system its probably worth waiting.
That I’d treat, as an on-hold activity – since we’d need affirmation, that multiple vendors are ready to entertain supply / viable selection [DDR5 / Mainboards / new socket CPUs]… been a while, since this much of a collective hardware change
