you’ve got a 7720 with a i9-9900K?
Are you sure those numbers are correct?
An 9th gen i9 is supported by windows 11
No, the i9-9900 is the desktop i use proffesionaly at the office.
The Precission 7720 is my personal laptop i have at home.
Both not win11 ready due to certain components that are not compatible.
Let say the price may vary between €2300 (quote 2016) and €4200 (quote 2019)? 
there are a few places to look for computer information etc.
one is Zach’sTechTruf he’s on Youtube, Twitch and Discord.
Discord is great as so much information and get advice on systems in chat.
Another great source to purchase is https://www.newegg.ca/ or https://www.newegg.com/
I would stay away from Amazon as it’s being reported spam etc. being loaded onto
computer systems’
And what’s your budget now?
Yeah, I’m in higher ed and we can only buy from preferred vendors. So Dell, Lenovo, Apple, etc.. I did slip in several years ago and bought an Asus laptop for using during meetings and site visits. It’s a 4th gen i7 and it’s still working. I’ve bought personal stuff from NewEgg for years and no issues.
Somewhere inbetween 2300 an 4200 euro?
I would preffer the 4200 where i guess my boss would preffer the 2300 
That’s a huge range. There are a lot of different possible solutions to this. The goal would need to be defined a bit more precisely.
SketchUp and Microstation. But the question of CPU or GPU rendering still needs to be clarified.
And if local AI models are actually supposed to run, then VRAM, RAM, and SSD capacity are particularly important factors. And memory, storage and graphics cards are currently the biggest problem in terms of cost.
A year ago, 128 GB of DDR5-5600 cost 300–350€; now it’s 1500€ to over 2000€ (including VAT).
By the way, that’s another point to clarify… does the budget mentioned include or exclude VAT?
I think the usage will be quite basic, as I said: 2D in MicroStation (AutoCAD style) and 3D with SketchUp. In SketchUp, we use the software/extension for sunshade analysis, and for our wind analysis, we have a cloud solution. So far, we haven’t needed realistic renderings. I also do some photo and video editing.
But since I cannot predict the future, it would be nice to be prepared for the worst-case scenario, where we do have to present realistic renderings, use AI functions more frequently like those being implemented in increasingly more software, import point clouds, import large and heavy terrain and building models created with third-party software, and so on.
Most AI functions typically don’t run on the machine , they are cloud services - if they do (which is less usual) they will normally run on the GPU or increasingly on an NPU.
So, no local AI and not much rendering.
That makes things simpler and a bit more affordable.(as far as that’s currently possible with these crazy memory prices…)
In that case, I’d recommend an Intel Core Ultra 7 270K Plus. It currently delivers pretty much the highest single-core performance (5,270 PassMark points - only the 285K is faster, for an extra €200) and acceptable multi-core performance
( PassMark CPU Benchmarks - Single threaded - All - Page 1 )
Alternatively an AMD Ryzen 9 9950X or 9950X3D, with slightly better rendering performance but lower single-core performance (PassMark 4,729 and 4,740 points)
Sample configuration:
CPU: Intel Core Ultra 7 270K Plus ~320€
CPU cooler: Noctua NH-D15 ~100€
Motherboard: MSI MAG Z890 Tomahawk WIFI (Intel 1851) ~250€
RAM: DDR5-6000 or 6400, 32 GB ~400€, 48 GB ~550€, 64 GB ~800€
SSD: Western Digital WD_BLACK SN8100, 1 TB ~230€, 2 TB ~360€
Graphics Card: GeForce RTX 5060 Ti 16 GB ~600€, RTX 5070 Ti 16 GB ~950€
Power Supply: e.g., Seasonic, Corsair, or Be Quiet 750W–850W ~100–150€
Case: e.g., Fractal Design Define 7 Solid ~150€
Various levels based on these components:
Minimum: 32 GB, 1 TB, RTX 5060 Ti, 750W power supply (~100€) = ~2150€ (1807€ excl. VAT)
Mid-range: with 48 GB, 2 TB, RTX 5060 Ti, 850W power supply (~120€) = ~2450€ (2059€ excl. VAT)
Maximum: 64 GB, 2 TB, RTX 5070 Ti, 850W semi-passive power supply (~150€) = ~3080€ (2588€ excl. VAT)
It depends entire what you’re using it for. SketchUp is an Application that only uses a single core. In that regard a Mac will save you much better because its single core performance (even with its cheapest processor) is outstanding (M5 single core = 4,340, a18pro (Neo) = 3,597). I use sketchup comfortably on a MacBook Neo for $500. But SketchUp software on Mac doesn’t have as much integration as PC version (revit import, Trimble etc). If you’re planning to do rendering with it, then you definitely need high multicore performance. Also, AI proofing is very unpredictable. It really depends on where you think AI is headed. If you think cloud based LLMs are the future then you really don’t necessarily need much local compute power (but you’ll pay through the nose for your future AI subscription). If you think, like myself, that cloud based LLMS (chatGPT, Claude etc) are in a devastating bubble waiting to crash, then you need a processor that can work well with an onboard local LLMs. For the price the Mac ARM chip architecture simply can’t been beating in this regards (but you need a hell of a lot of RAM (min 64gb)). In any case if your future proofing consider going with ARM chipset instead of x86 as that is where the industry is headed.
Thanks for all the advice i could add to my answer about the quote.

Our system administrator will be coming by soon so that we can go through the system once more in person.
That CPU looks quite a big step up in single core performance.
Better be prepared for future system requirements for the next 7 to 8 years, right? 
I can’t even imagine how the world of technology will look 8 years from now.
Skynet may have gone live by then .
If I didn’t have children this would be my hope…
Have you tried codex?
I’ve never gotten more than 2-3 years out of a work PC.
But I generally get 5+ working years out of my Macs, and another 5 where they serve as backup or in the case of my laptop they work fine for all my other tasks.
