Are you sure you want the CPU fan to blow the warm air INTO the case?
Usually you'd want the warm air out of the case ASAP.
The way you have it now, CPU fan and rear case fan are basically working against each other.
It can be easily changed though by mounting the CPU fan to the other side of the CPU heatsink.

Your RAM isn't running at 3000Mhz, it's running at 2133. You need to go into the UEFI setup and select the XMP profile to enable it. You should find this in the Overclocking section.

You should have bought a Threadripper cpu... more future proof.
Other than that, yeah, memory was set as default 2133 like another said.

And... if you have a high core cpu, it would make sense to use the cpu to get higher quality encoding... the nv enc would use the video card to encode while the cpu would just waste time doing minor work like potentially decoding video, applying some effects like overlay subtitles over image frames, rendering images on the preview window in Vegas etc.

May want to check into converting all your videos into an intermediary format that's known to be decoded in hardware for faster video preview and jumping in timeline, i forget now the format, i know it's been recently standardized ... that blackmagic codec , i forget the name.

1. Yes, Threadripper 1900x is pretty much useless as it is still an 8 core CPU like a Ryzen 7 1700(x) or 2700(x), the only advantage is more PCIe Lanes and quad channel memory.
And also Threadripper would make for a better video because you could show how to insert the CPU into the socket. Yes, that is special. And you need a screwdriver for the installation (According to AMD, comes with CPU).
But you had to get at least the 12 Core (1920) - wich wouldn't be much more expensive but give you 4 Cores or 8 Threads more than you have right now. The 1950x is at around 763€ and has 16 Cores, the 12 Core 1920x is at around 526€
The i7-7820k is at around 450€ so around double the Price of an older Ryzen 7 1700. The 2700 (NEEDs 400 Series AMD Board or a BIOS Update for wich you need an older CPU) is at around 275€ right now...

2. Best Bang for Buck would have been a Ryzen 7 2700 or 2700x - with a decent board that one would be around 200-300€ cheaper than what you got.
The i7-7820k is just eating electricity and runs hot as hell while only being an 8 core/16 Thread CPU - the same as a Ryzen 7 wich would cost almost half of that.


3. I think storage could be important and a higher end Board could make sense - because of the m.2 Slots it comes with.
What I'd do for a high end Video Editing thingy would be two 512GiB NVMe SSDs, maybe 1TB _AND_ an additional S-ATA one. With the latter only looking for good price/size ratio. A 128GiB is totally OK for it. It only needs to boot Windows. Working you should on the NVMe Drives. And use one as the Source and one as the Target. Like in the good old days with the 3 HDDs: One for Windows, one Source, one Target.

4. THe Power Supply doesn't look too good either. I think its an old, group regulated thingy.
For a System like that you should looked at 80plus Gold or better Platinum units with DC-DC (well, almost all do that) with an LLC-Resonant mode converter. The nominal efficiency of a somewhat decent PSU these days is 90% and voltage regulation is in the 1% area, 2% is considered not that great. And Ripple we are talking about something like 20mV or less on all rails with really good PSU...

Should have got the YUV RAM, not the RGB.

@Stefan Payne

you do raise a couple of good points..
i found the vid funny as hell.. every few min hearing Dave state “i don’t care” and “everyone is an expert” ahahah..
guess he has bin bombarded with suggestions by now..

My first thought was finally a subject where i don’t feel like the blond girl in the room.
i have bin watching Dave for years now, with 0 to little knowledge about electronics.

Just recently i started to get in to electronics and soldering. Because i wanted to be able to assemble my own mechanical keyboards..
it’s about time being 42yr old..

There is no such thing as the best computer.. it’s always a matter of use case..
interpreting performance graphs is as much of an art form as knowing what your’e doing.
being an it professional for the most part of my life one thing i can tell you nothing is
as simple as it looks..

points you made are valid..my thinking was along the same lines. Like
“why is David comparing a 8-core cpu with the threadripper and not the ryzen 2700 or the 1700”

When i saw the 1700 thermal profile vs performance a year ago i was so impressed and i still am.
i do think the improvements to firmware mem management not to mention the iommu makes investing in the new 2700 worth it.
i usually don’t meddle in the choices someone makes when it comes to hardware hahaha..
Like Dave everyone seems to think they are experts.. i think there are levels of experts..
like electronics there are the amateurs , the fancy hobbyists, and then there are does that make a living doing it work. ;-) wink,wink...

in your case i think fancy hobbyist or it pro ...my compliments on your comments all valid points..
CPU heat, and power supply all good points..

Only thing i would add to someone ELSE looking to build himself a new rig.

1) compare pricing AMD vs intel + look in to cooling performance core’s
2) if you have specific needs concerning memory keep in mind AMD does a bit of fiddling when it comes to mem.
it has to do with inter-core communication and the infinity Fabric.
Basically the speed of the infinity Fabric is linked to the memory speed.
Also i was told that the newest gen cpu’s are still going to be supporting Quad channel mem
so only two of the CCX modules are going to have direct mem acces the other two will have to go through the infinity fabric..
my good youtube friend “Thinkering With Terrius” raised that good point in his Computex Keynotes..
Really smart guy you should checkout his channel folks..
(don't forget Intel has to deal with the same problems when it comes to core communication)

3) power supply only settle for full modularity , and a good name brand..
last thing you want is to have to fiddle with cables if you power supply fails on you.. Plug & play is the way to go..
Just unplug the old send it for warranty work plug in the spare one you bought and rock on.. (happend to me once)..

4) cooling nothing beats Noctua yah it’s more expensive but noise vs airflow .. stop waisting your $$ buy good fans..

5) i have yet to find a batter case then the Fractal Design series.. i want silent and good airflow..
only better options would be the high end customisable cases..Were talking several $100..

only thing i miss is the use of nice 200M fans to run in front of the case..

6) don’t bother with fancy cooling paste.. if you buy a high end cpu cooler from Noctua they have tested their coolers with the paste they provide..
Don’t mess around with other stuff.. (it’s a whole world in it self don’t get lost in it..) being able to repast your cpu cooler every 5 yr or so would probably be of more benefit. not as much as you would think but still better then all the fancy compounds would give you..

7) And finally only install Windows if you need it for a specific reason.. simple office work like word,excel,mail plus browsing can be done with a nice linux operating system..

i’m a linux admin and like most Good linux folks we love to help people transition to OpenSource software..

I'm an expert and you're doing it wrong!  8)

Motherboard goes into the case first because it needs the metal shielding in the back when you plug other stuff in. Leaving it on the table makes electrons able to escape from the backside and possibly take some magic smoke with them.

@EEVblog
You really should dial down the "i dont care" attitude. Yes there are those ppl who just want you to make decisions according to their tastes, but not all of the posts saying you chose the wrong thing('s) is written by them ;) . BTW just done some digging around and it turns out a 1700X would've been better if we take into account the huge premium on intel boards ;) .

Ryzen 2700x would have had very similar performance for fraction of the cost (heck you can even get a Ryzen 1700 for even less if you don't mind overclocking for similar performance). Basically you could have gotten a similarly performing Ryzen system Motherboard + CPU for less money than the x299 motherboard cost you.

7820X does have twice the memory channels (4) but I recon with only 8 cores, memory bandwidth isn't tasked during encoding, because encoding is more CPU intensive than IO intensive in general.

So you can build a much cheaper system (half the price or less) with very similar performance for the use case going with AMD. Even going with Intel's own consumer CPU 8700k would have made more sense.. yes two less cores but the core speed makes up the difference and you don't have to pay the premium for a HEDT motherboard.

Or.. Threadripper 1950x.. would offer same 4 memory channels, which this time would actually make a difference since we're talking twice as many cores and threads. Threadripper would be almost twice as fast for about $200 extra.

I would have gone with Threadripper, because this is exactly what it's made for. It's also a new platform with longer term support AMD introduced with their brand new Zen architecture.

Perfect example of why AMD struggled for so long. Because even when they have superior products in every single way, people just don't do proper due diligence and research.

In his use case, the intel platform would be better, and the main thing I would change on that system, is the heatsink. He should use at minimum, a NH-D15, especially since he will need to overclock that CPU to get the most out of it.

GPU encode needs the fastest possible single threaded performance or the GPU encoder will get stuck waiting on a single thread to feed it.

Hard to believe it takes 16 CPUs running at 60%+ just to feed the GPU with data.  :-//

He's not using GPU rendering. Besides GPU rendering is limited (in terms of supported settings) and the lower quality of the final product compared to CPU rendering.

If all the 4K encoding is done by the graphics card...   would it not have been enough to upgrade the graphics card in the old machine, and get similar performance?

Fanboys or not, 7820X + x299 mobo is a one piece of turd performance/system cost wise.

As for the PSU:
http://www.realhardtechx.com/index_archivos/SILVERSTONE_Essential_series_ET650_B_650W_4.html

Its as bad as it gets. 8pin Protection IC -> usually no OCP on any rail, no UVP on +12V either.
Capacitor Choice doesn't look that good with JunFu/CapXon
Since I don't think there is any AVL from Silverstone for Cost Reason, it is possible that some units might even have ChengX capacitors - like my CWT GPS-750V has...

Exactly.

And there is one thing I forgot to mention:
In the early 2018 there was a huge bug found on Intel called Meltdown and the similar Spectre ones.

The Problem is that the Fixes of that hammered the I/O Performance.

And with those Bugfixes, you can't compare the performance from last year to now because they cost Intel quite a bit of performance.
And to make it worse: More is in the Works...

And with Video editing, we are talking about something that really uses I/O transfers...
