Not parent, but I've built my own computers for almost 20 years.
As the articles author himself questions, he should have gotten the marginally more expensive CPU, and definitely the GPU with more RAM.
* The overclockable CPU doesn't just mean that you very easily could get a 10%+ performance boost without much work, but also that you often (depending on your specific chip) can lower the voltage and make it run much cooler/quieter, which is something I increasingly care about if I'm using it a lot.
* He writes that fitting the model in RAM is basically the most important part, but then saves less than a dinner out by basically halving the RAM on the GPU he bought. The chip is otherwise the same though, so performance is only dependent on whether you fill that RAM or not.
* The Noctua D15 the parent mentioned is a CPU cooler where Noctua is a long standing high performant brand, and D15 is a specific model with a 15 inch fan and comparable sized heat sink. There are of course other brands, but I myself also usually end up with Noctuas. The reason it's important is that however fast you can dissipate heat from the cpu/case, the less chance of throttling, and the larger headroom for potential overclocks you get.
Airflow and room for larger heatsinks is also why he recommended not going for an ITX. A linked benefit is again the potential for a quieter system.
I haven't gone much into ML (yet), but I currently have a system with:
* I7 6700K (the difference to I5 6600K being higher base clock and hyperthreading, which is more important to computational work than to gaming, so if you have the money, definitely go for the I7)
* 32GB DDR4 (as author mentioned, RAM is cheap). The clock/timings on RAM isn't really as important, but try to find the best you can find for a given price point.
* An Nvidia GTX 1080: It's not Titan X or Z, but almost, at less price. It definitely blows the budget for a $1000 system, but I agree that the entire 10 series is good.
If the limit is a firm $1000, I would get something like this:

And if more funds is available, I'd get more storage and RAM, then a better CPU, then a better GPU, then maybe bump the chassis up to an R5 (same brand), possibly another motherboard. In that order. There's always something better, so you compromise based on budget.
- IanCal 10y agoI've got a near identical build, and my process was the same as you. I added a decent pcie nvme drive, and spent more than I guess I could have done on a motherboard that supports up to 128G ram so I can extend it later. I'm waiting for ram to drop in price a bit, or to hit a problem where I need more than 32 sooner, before bumping that up and probably adding more storage. It's been great sshing in from my laptop, submitting a job that completes far more quickly and keeping my laptop cool.
- croon 10y agoI kept my old 512GB Samsung 850 Pro, but will definitely get an nvme when I need more space/speed. Getting another 32 RAM will hold me over until I'll build a new one, so that part I'm not worried about. Yeah, it's supremely fast, my only regret is not having enough time to do something fun with it. For work I'm stuck with the clients platform approved machine, which is not what I would've picked. Tough to complain, but if I'm ever between contracts, I'll likely get into some fun project.

- hermiti 10y agoI have a machine that I am using for deep learning and it has 32GB of ECC RAM paired with a Xeon CPU w/ Quadro, and that 32GB of RAM is gone almost instantly. Now I'm looking at building another machine as it has gotten to the point where I am spending a great deal of time waiting. I would be interested to see what other people are using for their setups, and how that can differ for things like high-resolution style transfer or generic neural networks, etc...and at what point they have to switch from geforce/quadro cards to tesla.
- mamcx 10y agoWas years ago when I build my last PC and I'm out of the game. I'm tempted in build a hackintosh: https://www.tonymacx86.com/threads/hackintosh-cutting-edge-kaby-lake-nvme-ddr4-4k-viable.214249/#post-1433129 https://www.tonymacx86.com/threads/hackintosh-cutting-edge-k... - Intel i7 Kaby Lake - No decided on motherboard. The one that cause me less trouble (for hackintosh) is fine. - GTI 750ti (have) or buy a pascal nvidia. - NVMe drive if possible - 32 GB RAM. - Probably a Thermaltake CORE P3 case. Not decided. I was thinking in use a Liquid Cooler but wonder if the Noctua could be better/less noise?
- croon 10y ago> I was thinking in use a Liquid Cooler but wonder if the Noctua could be better/less noise? Depends, is your option of water cooling an All-In-One-solution that have become popular in recent years? Their performance is on par or slightly better than a large heat sink + large low speed fan(s), but they're not generally quieter, as you still have fans for them, as well as a pump. I considered those options when building mine too, and as I wans't too enthusiastic about assembling my own water cooling system, I went for a large air cooled heatsink instead (the D15). No risk of leakage or pump failure, and proven performance/low noise.
- mamcx 10y agoI was planning in use Corsair Hydro H60 (http://amzn.to/2k9a9O1 http://amzn.to/2k9a9O1). However, I wish to have a quiet system, and my brother have it and it sound louder than I wish. I don't plan on overcloking.
- croon 10y agoYeah, that's one of those AIO water coolers I was referring to. http://www.anandtech.com/show/5054/corsair-hydro-series-h60-h80-and-h100-reviewed/6 http://www.anandtech.com/show/5054/corsair-hydro-series-h60-... The "Silver Arrow" is an air cooler from Thermalright that is pretty equivalent to a Noctua or a Phantek or be Quiet! etc. In that review it beats the H60 in both temperature and noise. The H60 is more than twice as loud. So yes, unless you assemble your own water cooling system, I'd say definitely go for a regular heatsink+fan.
- EvgeniyZh 10y agoAgree with a system you've linked. I believe 1060 has best price-to-value for deep learning in the market.
