Small-Scale Question Sunday for May 10, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Can any of the tech nerds on this site recommend a reasonably high-powered computer? My laptop died two weeks ago, and my 10-year-old desktop just isn’t working out for me. Despite commenting on a Rationalist-diaspora forum, I’ll admit to my shame that I know almost nothing about computers, and I’ve pretty quickly become overwhelmed by the staggering number of options for each and every component part.

What I’m looking for is a machine that can ideally simultaneously handle several open Word documents, Excel spreadsheets, image files, and PDFs, one or two PowerPoint presentations, an ungodly number of open tabs spread throughout multiple windows and likely across several browsers (including several active windows that are absolute memory hogs), a CAD program, SoundCloud, and a couple of other minor programs on a rotation basis. My budget is roughly $1,500–$2,500, though I’m open to being told that I need to increase it. I basically want a machine that will handle everything I throw at it and won’t die or get completely bogged down at any point in the next 15 years.

I don’t mind buying either a desktop (in which case I’d supplement with a cheap laptop for those few occasions when I’d need one) or a laptop. In either case, I’ll be hooking up several monitors, a keyboard, and a mouse. Also, I know it’s a bad time to be buying a lot of memory, but that unfortunately can’t be helped. Finally, without any additional information, I was planning on just picking one of the recommended gaming desktops on a review site, but I’m hoping someone here can tell me if that’s a good idea or not.

Can you say what the CAD program is? SolidWorks has drastically greater requirements than FreeCAD which has greater requirements than OnShape, and the closer you get to (or above) the first side of things, the more it's going to control your requirements.

For RAM, I'd suggest a minimum of 16GB and ideally 32GB for your use case, with a minimum of two sticks (because of how DDR works, there's a significant performance penalty to 1x32GB vs 2x16GB). Given current RAM prices, I'd personally want to wait for later and upgrade when RAM prices drop - it is the single easiest component to upgrade - but I recognize that may not be possible for your use case. Still, be aware of things like how many slots your motherboard has and what max memory the CPU supports: a motherboard with support for four sticks of RAM gives you a lot more options even if you think your starting value is good.

I'd recommend the desktop-and-disposable-laptop combo, unless you have strong business requirements for CAD-on-the-go. You can get a well-refurbed ThinkPad T480 or E15 around 300 USD; getting a powerful desktop's equivalent specs on a laptop will cost you much than that, and will be a much worse use experience at the desktop, and be harder to maintain.

I'd also consider whether you want a pre-build, or want to build your own. Most prebuilt gaming machines are going to optimize for a use case that isn't yours: gaming generally favors more GPU and less RAM than even the SolidWorks use case will want, and many CAD programs are (still) extremely single-thread-heavy in ways that gaming has largely moved away from. That said, there's not a massive price penalty compared to the same CAD performance in new workstation machines. Building your own can save more money (though it will probably take some careful looking at mobo-cpu-ram combos right now), but it does mean following the instructions or video guides carefully, and using a tool like PCPartPicker to keep an eye on compatibility problems.

I'll... also caution that trying to future-proof for five years is doable and probably easy, ten years is plausible, and fifteen years is an exercise in frustration. The Computer Of The Future in 2011 would have involved a 80GB-256GB SSD for your operating system drive, a first-generation Core i7, and 8-16GB RAM. I actually managed a handful of these for office work, and even without the CAD requirements, they bogged down bad by 2020, and that's with repasting, cleaning, dusting, drive upgrades, and psu replacements.

Thanks for the detailed response!

I have previously been using an old non-subscription version of AutoCAD, but I’m not sure the budget will support paying for a subscription moving forward, so I’ll need to switch to something free/cheaper. I was thinking most likely FreeCAD.

Also, I’ve never built a PC before, but the actual process doesn’t seem very difficult; rather, it seems that the difficulty is in knowing what parts to pick. Between your and others’ advice, netstack’s link, and PCPartPicker, that aspect seems to largely be covered. I’m open to either buying a prebuilt or building from parts though.

You're running Windows, I presume? Is portability a concern for you?

I am quite happy with my Asus Z13 Flow with two exceptions: it's quite noisy under load and it eats through its battery quickly even when idling. However, it can handle anything you throw at it.

My laptop was a Mac and my current desktop runs Windows 10. I have found over the years that are very few occasions when I actually need a laptop, so portability isn’t much of a worry. I’ll have to look into the Asus though.

I'm similar. I have a desktop and a chromebook, and that covers all of my needs. Before that, I had a beefy laptop that sat under my desk, plugged into a full-sized keyboard, a mouse, a bigger monitor with good ergonomics, and speakers. It baffles me when I see people with a dedicated space to work on a laptop that's set up like a laptop.

Framework Desktop has the same guts in desktop format, but you can get a better or cheaper desktop if you build it yourself. I agree with @netstack's assessment that the 1500 and 1700 tiers at LI are good.

My own build started from https://www.logicalincrements.com/. The idea is that each row of the table consists of parts which are roughly aligned in performance. Everything within the row is cross-compatible, so if you find a sale you can swap it in. I’d look at the $1500 or $1700 tier; it should manage your use cases just fine.

Thanks for the link! That looks extremely helpful. I also appreciate the advice on which tiers to examine.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
