get a 1050Ti with 4GB vram, 2GB is quite on the edge for todays standards even at 1080p and if you want some futureproof into it.

i3-8100 is fine, but if you do other tasks with your PC also that need more cores you might want to check AMD cpus.
Ryzen 1500X for example is with a similar(about 30 more) price to this but has 4 cores and 8 threads and possibility to overclock even with the default stock cooler to about 3.8ghz, with 20-30€ aftermarket cooler 3.9-4.0ghz.
what is you total pricerange?

something like this: https://pcpartpicker.com/list/Cb9wV6

motherboard can be cheaper, rams you can get a bit cheaper even and PSU can be cheaper and ofc monitor can be cheaper, you didnt detail what you exactly want, what size, IPS/TN/VA whatever?

i didn't include keyboard/mouse cause you didn't list what you expect from them, mechanical? gaming? RGB?

I am not determined against amd cpus. But I am towards the i3, because
a) it is cheaper, it is a lot cheaper where I am, or more precize ryzen are a lot more expensive than they should be, but I have not really checked the different price for motherboard and memory.
b) I like that it has an igpu although not really needed
c) maybe I am FUD victim because of: https://www.gamingonlinux.com/forum/topic/3207

I am not a hardcore gamer and I do not have any special requirements for keyboards/mouse. I do not really need advice for that. I need some advice for monitor. The monitor will be 1080p for sure and 22-24'' no doubt. But I know very little about the other specs. for example how different is 1ms to 5ms? I have no idea. I am not a hardcore gamer and I will not through too much money but I want it to be a decent system.

Those freeze issues are not a concern for newer cpus and if you want with IGP then Ryzen 2200G is around 99€ comes with GPU thats more powerful than any intel offering.

the thing with i3 is, that its fine for most games but its not futureproof at all and as we all know intel likes to change sockets, so later when you want to upgrade you have to get new motherboard etc.. AMD said they support the same socket with all upcoming processors until 2020 iirc. also more cores is good for vulkan api and having your OS have some breathing room for other tasks. thatshy i would pick ryzen myself.

about keyboard mouse, just buy some cheap ones then :)

monitor 1ms and 5ms you probably dont feel the difference 5ms is usually IPS panels with better color accuracy and 1ms is usually TN panels with less color accuracy.

CPU: In my opinion the i3-8100 isn't worth it, The new AMD 2400G performs on par and in some cases even beats it without going much higher in price. More than that, you also have 8 threads which provides a better all round environment for multi tasking. Since there's a big price difference at your location I can understand why you'd want to go with Intel, in part I have the same issue in my country (Malta), it seems 90% of computer shops here are Intel fanboys and they only stock Ryzen 1700 or better CPUs, anything mid-low range is either overpriced or "on order".

As a bonus you also get a great iGPU with the 2400G, while it's still a bit rough on Linux, it will get better in time just like a fine wine. As for the freezing thread you linked, 10 days ago I updated my bios to the latest and haven't had a single freeze so far and I do torture my PC quite a lot when it's on. Even before the bios update, I had the freeze like once in a week. I don't think 2nd Gen will be affected by this.

GPU: AMD Linux supports keeps getting better and better, if you will be running Arch (as suggest by your distro icon) I don't think you'll have any issues upgrading Mesa. However should you go with Nvidia, the 1050 Ti is an excellent choice, also agreeing with Xpander here, 4GB is pretty much needed if you plan to play modern games and if you want it to last a bit longer.

Monitor: After being a TN panel user since forever, last year I switched to an IPS setup and the difference in colors is incredible. Don't let that "5ms" scare you.

Case: Don't cheap out on the case, look for something that has filters in the front, the top and under the PSU. Also make sure they're easily removable for cleaning. I once made the mistake of buying the cheapest case I could, big mistake as it was a dust magnet and cleaning it was a pain. I'm running a Corsair 400C which so far I found very good, the insides barely got any dust in almost a year and it's easy to take apart for cleaning. The Fractal Design - Define C is also another of my favorites.

Edit - removed

Thank you very much for the help, the info about the monitors was usefull :) I would still like some more advice about the PSU and motherboard, what should I be really careful?

About the CPU. In my location the prices and availability are a bit different. My choices currently (I will have to see that again of course as I will buy the desktop probably in a month)

a) i3-8100
This is the only meaningful choice on that price range

If I am going to spend some more money I have three more choices

b) ryzen 5 1500X
c) i5-8400
d) ryzen 5 1600

this is actually sorted by their price(!) although they are close.

ryzen 5 2200G here will be more expensive than i3-8100 and I do not see it to be any better
ryzen 5 2400G is a bit more expensive than ryzen 5 1600 so probably does not worth it.

Motherboard choice is tricky if we havent decided on the CPU yet. if you go with i3 8100 then some super cheap intel mobo will do i think as this cpu is not overclockable anyway. I still wouldnt recommend to go with i3 these days, i5 minimum or ryzen.

PSU, you probably want quite cheap also and not chasing modular ones. get anything from 500W and up and 80 plus bronze or up i'd say.
do not buy noname ones though. Common brands: Corsair, EvGA, Cooler Master, Seasonic, Silverstone, Thermaltake.

I have a 400Q which is quite similar and it’s definitely not worth the high price. It’s supposed to block noise but it doesn’t, the ports on top get all the dust, the filters are hard to remove and the HDDs are only accessible from the right :-/.

I can vouch for the Fractal Design Define series, but they're not exactly cheap. I've got the R4, and the front filter is really easy to clean. The bottom filter doesn't need cleaning because the PSU (Corsair RM750) basically never spins up. The case is also super quiet.

I checked it out, it seems to be non Windowed version of the 400C. I paid about 105e for mine which is acceptable for what it offers. Removing the face to access the front filters isn't very practical but at least it gets the job done. I've had this idea of using an open air system for my next build, it will either be make or break with the dust problem.

For Linux builds, I tend to favour AMD CPUs as the multi-core performance is generally more useful and they dissipate heat a lot better than most Intel CPUs. :)

yeah, but singlecore perf still dominates when it comes to gaming, but ofc if you pair your cpu with lowend 1050Ti then it doesnt matter that much. But Ryzen for sure is more futureproof when you can get more cores with the same money.. that 10-15% weaker singlecore perf (mostly due clock speeds) is not really a issue unless you have GTX 1080Ti.

and yeah like i said before, more cores gives more breathing room for OS also if game utilizes few of them and OS can use the rest. Better for multitasking etc

Adding my own voice to the comments earlier:

If you are severely restricted on finances, then I personally would try to find something secondhand, e.g. a Core i5-2400 system that someone is letting go for $150 and then put some semi-decent graphics in that, e.g. GTX1050ti 4GB, GTX1060 6GB or AMD RX560, RX570. At least the graphics could then shift to your better machine when you can afford it.

If you really want to go latest tech which is upgradeable in the future, when you can afford it:

Recommend the MSI B350 MATE motherboard for Ryzen CPUs (about $100). Get whichever Ryzen you can afford, with prospect to upgrade it in the future. I personally really like the Ryzen 5 1600 which comes with the Wraith cpu fan, and is good to overclock (and lots of cores, about $250). Recommend get a single stick of 8GB DDR4 RAM, and potential to upgrade with 1-3 additional DIMM modules in the future. Noting that this motherboard also has a NVMe slot for really fast solid state drive in the future too.

Then once you have the machine based on Ryzen, as per above, get what graphics you can afford (even, say a secondhand GTX960 or GTX750ti or whatever) and use that until you can afford better.

g000h's above suggestion is really great if you're on a budget. I have an i5-2400 system with 8GB ram / GTX 760 which still packs a punch in today's games. I checked a few benchmarks and it seems to be on par or slightly slower than the Ryzen 1200, not bad for a 7 year old CPU.

Considering how you seem to be aiming for an i3-8100 in the first place, it would be a good idea to look for a used i5 system, that way it might leave you with some options such as better GPU or a cheap SSD.

I have seconds thoughts about the nvidia and thinking I would like to have amd with mesa instead. the RX 560 (4GB) has about the same price as gtx 1050ti. How much worse would you think I will be with it? (currently I am planing to buy in three weeks, hope the prices fall a bit more)

RX 560 is decent, but actual result depends on your native resolution.

Quoting: ShmerlRX 560 is decent, but actual result depends on your native resolution.

If you ask about the monitor, as I said I am only interested in 1920*1080

Quoting: lucinosIf you ask about the monitor, as I said I am only interested in 1920*1080

That would be fine IMHO.

Excuse me for asking again, the question is how would you compare a RX 560 and a GTX 1050 (Ti) for gaming on linux. (How much more or less problematic is any choice and how much worse or better is the performance.)

if you are going to be using KDE, go with AMD, it has issues with nvidia drivers. As for Gaming i think you will have slightly better experience in terms of support and performance with nvidia.
So basically its all up to you which you want. Both should be fine enough with both their own small issues

Some advice from me, and I build lots of PCs.

My preferred price/performance is the Ryzen 5 1600 which comes with the Wraith cpu fan.
My preferred motherboard is the MSI B350 MATE which works very nicely with the Ryzen above.
(You can overclock the 3.2GHz R5 1600 to 3.6GHz on the Wraith, no problem, on this board.)

This motherboard supports 4x 16GB DDR4 RAM (I tend to go for 2400MHz speed, for value for money.)
This motherboard has a NVMe PCIE SSD slot, for getting 5x speed of SATA SSD drives with the right SSD.

I am using the above components with an Nvidia GTX1080TI on Debian Linux 9.x - no problem.

Recommend Nvidia GPU with as much speed and RAM as you can afford, e.g. GTX1060 6GB (not 3GB).
