Xeon E5 1620 V4 or 2620 V4 for Video Editing?

Hi there,

I'm building a PC for 4K video editing on Adobe Premiere Pro and DaVinci Resolve. It's my first time building a PC and it's been a learning curve.

I am considering two CPU options for my machine: Intel Xeon E5 1620 V4 or 2620 V4, and trying to decide on one. 1620 V4 is quad-core 3.5GHz/3.8GHz Turbo and $100 cheaper. 2620 V4 is 8-core 2.1GHz/3GHz Turbo.

Should I go with the higher core number but slower clock speed or lower core number and higher clock speed? I've read different forums and pretty much everyone says to go with more cores, but I'm worried that 2.1GHz is too slow... One article I read said core number performance plateaus after 6 cores when running Premiere Pro. Any thoughts?

Another thing I'm deciding on if ECC RAM is worth getting for the kind of work I'll be doing, or should I stick to non-ECC? Thoughts?

I'm getting X99 chipset and an 8GB Radeon Pro XW 5100 GPU.

Thanks!

X99? Then E5-1620 v4, since you cannot use dual CPUs anyways. Get the Asus X99-WS motherboard so you can use ECC. And I won't suggest the Radeon Pro WX 5100 unless you have some render GPU on hand.

I used PC Part Picker to build the PC and was kind of following components' compatibilities. Building a dual CPU machine is out of the question because it would be way over my budget and I honestly don't think it's needed for my software requirements.

The motherboard I'll be getting is Gigabyte GA-X99-UD3P (rev. 1.0) because it's the most affordable option. All Asus X99-WS are way too expensive for me, except for the X99-M WS. Reading its specs, it should be sufficient. Are you recommending it just for the ECC compatibility?

Why won't you suggest Radeon Pro WX 5100? Can you please elaborate? I'm choosing it primarily for DaVinci Resolve.

I'm updating this thread for the curious. I took okcnaline's advice went with Asus X99-E WS/USB 3.1 chipset (found a refurbished one for a great price), Intel Xeon E5 1620 V4 and 16GB ECC DDR4. I needed to upgrade the bios to get the chipset to recognize the CPU, but it all worked fine once it was upgraded. However, I stayed with my GPU choice and got Radeon Pro WX 5100 for now, and I'll see how it performs. I've had good experience in the past running Resolve on Mac Pros with Radeon GPUs. Pro WX series is relatively new so I decided to give it a chance.
