Nothing else has high clock speed and high core count at the same time. 4.6 / 4.7 / 4.8 GHz all-core on 60 cores at stock voltage is great for Photoshop / Lightroom bulk processing. The price per core and processing power density for a single user system is unmatched. It's great for 4K gaming as well and hits 5.2GHz with a mild voltage increase. Gaming is even better with Threadripper which does 5.7GHz PBO at stock voltage.

this is just showing off, nobody needs 4 Terrabytes Memory in one socket, 112 PCIe 5.0 lanes for 7 GPUs or 28 NVMe drives.
but is it a good room heater in the winter.
My desktop PC has a total of 16x NVMe drives for boot and ZFS, 2x GPUs, a 100 GbE NIC, and more. I used to have ZFS in a NAS, but my desktop was the primary client so I made it local for a big performance boost.
Can you get all the cores working for Lightroom? Latest versions of lightroom cannot do multi-threading of processing pictures in parallel.
In theory, software development, AI workloads and media processing workloads can take advantage of the cores and PCI-E lanes.
The problem is that software hit bottlenecks and cannot scale to all the cores. My old version of Lightroom used to work so great, processing my images to create previews in minutes.
I certainly wish I had a 60 core SPR-WS vs a 16 core when compiling pytorch/vllm!
It's nice to have so many PCIE lanes for a GPU workstation, otherwise yeah it's pretty overkill.
When bulk exporting photos to AVIF HDR, Lightroom uses 100% CPU with all cores at maximum Turbo. This is my primary activity in Lightroom - I don't use any effects beyond enabling HDR.
I'm not saying i could not use all the resources of a w790 mobo.. It's just very expensive..
My new setup is completely based on remote desktops though, primarily because of sunshine/moonlight streaming combined with the linux kernel EDID trick..
At my work table i have a single mini pc feeding 3x 4k screens, mounted behind one screen with a vesa mounting bracket.
There are zero cables or gadgets on my desk, or on my floor under the table
The big ATX cases are in a separate room running proxmox feeding GPU's over pcie passthrough, streaming overmoonlight sunshine to moonlight client, with no monitor cables attached, just a binary EDID file in the initramfs, and a kernel boot option.. Using nvenc, the remote 4k@60 desktop is indistinguishable from a 'real' image via DP/HDMI
I use CPU affinity alot in proxmox, i have a dual socket server where one CPU does h.264 -> hevc transcoding, the other CPU hosts the desktop VM's, and the GPU pcie lanes are routed to that CPU.. I tried many things, like allowing the transcoding run on some cores of the 'desktop' CPU, tried setting CPU shares and CPU time, but after awhile, the transcoding would start to slow the desktop VM down, presumably as the CPU cache filled up.. But just running on separate sockets works fine..
Next project is building a game streaming server, might be nova lake, but already on a cheap arrow lake core ultra 5, i would install one dGPU, have the gaming VM use all the P-cores plus maybe 4 e-cores, and then another desktop VM use the rest of the e-cores, utilizing the iGPU..
So a W790 system would be a dream for this kind of setup, but having a huge case producing massive heat next to me, no thanks.
I would like these kind of motherboards WITHOUT all the USB and other stuff not needed in remote computing..

Where are you finding a 100$ cpu for the board I'm about to build a system for a workstation using the Gigabyte W790 AI board and the whole build is like 5k$ Canadian, the CPU alone is 1500$
This is exactly what I build mine for: Lightroom.
Which version of lightroom do you have? I upgraded the recent one and Lightroom stopped working. Old versions was always utilizing all cores.
All the current Threadripper boards have terrible PCIe slot layouts. The AsRock W790 WS is still the best HEDT board.
Threadripper has easier overlocking with PBO that reaches 5.3 GHz on light single-threaded loads at stock voltage, but it downclocks under heavy load. If you force an all-core clock and voltage, you lose the high single threaded clock.
Sapphire Rapids can do 5.2 GHz for heavy single threaded loads with overvolting and it never downclocks. You can also force the maximum Turbo clock on all cores at stock voltage and it still never downclocks.
I'm trying to build a video editing machine. Attached is what i have so far for a build.

Which version of Classic ? I noticed the issue when I upgraded to the later versions so I want to see if it is due to my ES chip or lightroom problem. Btw, which CPU do you have?

Are you using your own funds or corporate/government funds?
Isn't video editing heavy on CPU? I bet my $120 56 core QYFU ES chip will beat that w5, even when w5 is overclocked. I also got my 32GB DDR5 sticks less than $100 from eBay. Those DDR5 4800 dimms can be easily overclocked to 5600.
I wish I had bought more though
Prices are still crazy high on DDR5.
