Advice for a Modeling/Rendering PC

Hello, I've posted here before and here I am again for the same reason.
Shortages and prices are chaotic atm, so my PC build has been halted, and in the meantime I made some slight changes before buying the parts.

Originally my budget was 2000 Euros, but let's say that the number might, or more likely, "will/is" fluctuating.


The planned build right now is:

CPU: AMD Ryzen 5 5600X


RAM: G.Skill Trident Z Neo 32 GB (2 x 16 GB) DDR4-3600 CL16 Memory

Storage: Samsung v-nand ssd 860 evo 500gb (Bought)
Samsung 970 Evo Plus SSD 1.0TB M.2 NVMe
Seagate Barracuda 2TB

GPU: EVGA GeForce GTX 950 SSC GAMING ACX 2.0 (Later possibly and most likely replaced with a 3080)

PSU: Corsair RM Series RM650 650W Full Modular 80 Plus Gold


The changes I made are the CPU and RAM.


Since I'm planning on using my imaginary 3080 for rendering in the future, I thought that maybe I don't need to pair it with an expensive CPU like the Ryzen 9 5900X.
I only need the CPU to have a smooth Viewport and I noticed in the following benchmarks, that the Ryzen 5 5600X is on par with the Ryzen 9 5900X.

But then I started reading the following article that got me worried -> https://www.cgdirector.com/best-hardware-for-gpu-rendering-in-octane-redshift-vray/
At first, my little brain got confused at the PCIe-Lanes and how "Different CPUs support a different number of PCIe-Lanes.".
And then I received a slap when I read that, "Some processes, though, that happen before and during rendering rely heavily on the performance of the CPU, Storage, and (possibly) your network."

So if it's not too much, can someone reassure me that the R5 5600X is good enough for Modeling/Rendering tasks (I really don't want to wait until prices go down on CPU's)


The RAM that I originally could have purchased would have been the following -> Corsair Vengeance LPX 32GB DDR4-3200MHz (CMK32GX4M4B3200C16).

After some research though, I noticed that the sticks "G.Skill TridentZ Neo 32GB DDR4-3600MHz (F4-3600C16D-32GTZNC)" are more compatible/better for the Ryzen processors.

So then again, I'm simply seeking for validation


The plan so far, is to gather all compatible parts and build a PC that can handle any modeling task.
It will temporarily host my old GPU (EVGA GeForce GTX 950 SSC GAMING ACX 2.0), and when the prices go back to being "reasonable" I'm planning on swooping an RTX 3080. So until then I'll be stuck with modeling (which I don't mind).

Yet again, here I am seeking validation from the Masters.


Thank you for reading, and also thank you for all the interesting articles regarding 3D Art.
I don't know how else I can show my appreciation, other than posting a low effort, copy pasted dancing figure :>

The 5600X is fast enough for GPU rendering. No issues here at all. Any 5xxx Ryzen CPU has high enough single core performance to not bottleneck your gpu processing in gpu render engines.

Mainstream cpus per see have less pcie lanes than hedt cpus. But with just one gpu this is no problem. This only gets interesting if you want to drive more than a single gpu for rendering.

You'll see hardly any difference between the two RAM kits you listed. That extra 400mhz at same latency will boost your performance within the margin of error in most workloads. I wouldn't bother sending the one back for a new one.

I see no issues with running on the old gpu for a bit and swapping it for a 3080 once you have it. The 650w psu is decent, though don't try to run both gpus with it as it'll probably be too weak.
