Note that for the modeling part you need the highest possible processor frequency, so the Xeon W-2225 at 4.1Ghz seems the best option, but on the V2 with these 32 of RAM, if your graphics card still works re-use there, it will save a bit if you can choose a tower without a graphics card (which is not uncommon on workstations)
Also see for SW2020 the minis that are recommended. (having stayed for the moment in SW2019 with a second-hand Xeon E5-1620 3.6Ghz - 32GB Ram Quadro K2000 station (400€ for information), I prefer not to go under 2020 which should be more greedy)
Where I work we have HP Z4 or Z440 stations with different processors and different RAM configurations (32, 40 or 64 GB) in DDR3 or DDR4.
For my part, I have a Z4 with Xeon W-2135 3.7 GHz processor and I think I should have taken a 4.1GHz but it will be for next time or for a colleague.
As far as RAM is concerned, I'm at 64 GB in HP 2666 MHz (3 x 16 GB + 2 x 8 GB)
The graphics card is an NVIDIA Quadro P4000 8 GB dedicated and 32 GB shared
500 GB SSD + 1 TB drive
Despite all this, it still lags. We are working on sorting plant layouts that can range from 100 pieces to more than 3000 without any problem and we are still on SW2019.
And today we looked with our IT service provider to upgrade in the coming weeks a station to 128 GB of RAM with 2 64 GB Kingston sticks.
I wanted to know if any of you had already done it or heard of it and therefore have his feedback, THANK YOU in advance
Assembly with several thousand components and works on the network without PDM (Sw2020 SP5)
So yes it lags but you shouldn't be surprised after a certain number of parts no matter the configuration, it doesn't change much in my opinion, there are still the limitations of the software.
But despite everything, the assemblies come out, you just have to be patient on these big assemblies.
For our part, we have a free station that we use to make large implementations (MEP or assembly) and this station allows us to free up ours where we work on sub-assemblies
To date, the largest assembly 180,000 components, including some rather large and very heavy step parts.
Most often 20-30,000 components on the overall plan.
