Hi, everyone. Forum noob here, looking for advice.

Here’s my deal: I used to be involved in hardware, and know how to put a system together, but my knowledge is ~4 years out of date, and now that I need to put together a workstation, I’m overwhelmed AF with the options. I need it for my design business, which is thriving (which is why I need a better comp) but it’s killing my spare time (which is why I’m looking for advice and shortcuts).

It’s going to be a graphics workstation - Sketchup, Enscape, CorelDRAW, AutoCAD, some Revit. So the focus isn’t on frame rate but on processing power, reliability, and graphics performance.

I have $ 2,500 to spend, can push it up to $ 3,000 if needed.

Maybe allocate $ 500ish of that for a NAS box with RAID 0+1.
Have a monitor I’m happy with, so that’s not a concern.

Physical space is not a problem - I want a huge tower or desktop, with plenty of space. Don’t care about RGB lights, actually prefer the “A/V receiver” blackout look. Not married to any specific brand, so either Intel or AMD, either Nvidia or ATI, doesn’t matter. Whatever works better for the money.

The main dilemma I’m struggling with is “invest in a stronger CPU or max out videocards”? Like, should I spend $ 1,200 on a Threadripper or should I get more GPU power and RAM?

Then, Ryzen vs Threadripper vs Threadripper Pro? Or… what else is out there?

Videocard - according to Sketchup and Revit forums, MOAR VIDEO MEMORY FOR THE GOD OF VIDEO MEMORY is a thing. But where do you stop? 8GB? 10GB? 12GB? At what point does the price increase stop making sense? Again, it’s not for gaming, it’s for keeping track of complicated 3D models.

Should I spend $ 700 on RTX 3080 with 10GB, or get the 3060 8GB and invest another $300 into more (or faster) system RAM?

Should I do 2 less-expensive videocards or 1 maxed-out one?

Is there a way to start with a decent stack of SSD storage and add more later on? Adding more modules in an “array” rather than replacing them with higher-capacity modules? What do people do if they know they’ll have more money to invest in a system later on?

It’s all these kinds of decisions, and it’s overwhelming… any advice, whether general or specific items, would be much appreciated!
 
Maybe something like this?

You dont need a threadripper for a CAD workstation. RAM and GPU VRAM all the way.

The case has 4 3.5" bays just in case.

The GPU can be scaled up with 2 of them and NV link if you wish to do so.

You're right, it may be worth it to scale down the CPU and max out the video card.

While exploring the 20-24 GB area, I came across the Radeon RX 7900 XFX, which apparently has a much better benchmark than the RTX A4500. Of course, we all know how reliable benchmarks are... but still:


Hard to find more head-to-head comparisons, I guess they're in different "areas of interest"?

The RTX A4500 looks amazing and the specs are nice, but every benchmark I found so far is telling me to go with the RX 7900 XTX. Am I missing something here, or is this a case of an "older but workstation-oriented" card competing with a "newer but desktop-class" card?

I bumped up the specs to fill out my budget, check it out:


What do you think?

(And yes, I need a UPS, the area I'm in has s**tty power, the current APC whines at least 1-2 times a day).
 
The studio grade GPUs have drivers and software optimisations for accurate rendering and operations in CAD softwares.

But if thats not a big concern, go with the RX 7900XT or XTX. https://pcpartpicker.com/product/N9...deon-rx-7900-xt-20-gb-video-card-rx-79tmercb9

And a few other pointers: you dont need a AIO for the 13700. The same for the Z790 mobo. The same goes for DDR4. You dont gain much with DDR5. Look for Deepcool AK620 or Thermalright Frost commander 140.
So i would suggest sticking with the B760 and DDR4 combo.

While choosing SSD, look for the pcie 4.0 model that have the highest in random read write speeds. Not sequential.
The Crucial P5 plus is a great choice and is priced right. Go for 1x 2tb for now and scale up if required. https://pcpartpicker.com/product/VZ...ie-40-x4-nvme-solid-state-drive-ct2000p5pssd8

I would also suggest getting 3 x 4tb HDDs just in case. not a single 12tb drive.

The case i chose comes with 140mm intake fans and are really quiet. has front panel USB C and is an overall a very good case design.

The case choice is a bit questionable. You dont really need a 1200W PSU. a 1000W is fine for a 7900XTX. go for the 1050w GF3.

I am not the expert in UPS, so i leave the UPS choice to you.

....and the same build but based on a Ryzen 9 7950 X3D, because IDK, something about the 3D V-Cache is hitting a geek nerve.


If you like cube type cases, have a look at O11 dynamic. https://pcpartpicker.com/product/Ykytt6/lian-li-o11-dynamic-evo-atx-mid-tower-case-pc-o11dex

And again, a B650 mobo will be more than enough: https://pcpartpicker.com/product/WB...te-ax-atx-am5-motherboard-b650-aorus-elite-ax

X3D is helpful in gaming. not usually in CAD softwares. Again, have a look at benchmarks before deciding.

Any particular reason? On-motherboard RAID, like 2 drives striped & then the pair mirrored for reliability? Or 4 drives striped?
