    Do I have to take something into account before buying a GPU? Like RAM type, socket, etc...

    Not really. Just make sure you account for bottleneck, power supply, physical space, and PCIe slots.

    PCIe? Bottleneck?

    Bottleneck: your CPU or GPU outperforming each other. There are calculators online for it.
    PCIe: the name of the GPU slot.

    Make sure your PSU can support the one you want to buy and that you're not buying a crappy one
    Don't buy anything from the 7 series anymore

    So, how can i know that my PSU supports it? How can i know what PSU i'm using?

    Bottleneck is very misleading and usually wrong, especially with BeamNG no generalizations like such work at all.

    While it is true that faster GPU needs faster CPU to feed it, all that is very game dependent and with BeamNG nothing is like with other games.

    Doom game that uses Vulkan and is pretty much ignorant of single core computing power because of good threading is totally different from BeamNG which relies mostly on single core performance to feed GPU.

    Even 8086k can be a bottleneck for gtx1050Ti in BeamNG, it really depends quite a bit from several factors.

    So I recommend ignoring whole bottleneck mumbojumbo and just getting GPU between gtx1050Ti and gtx1070 performance levels. For CPU best performance comes with intel K-models, i3-8350K being very good 'budget' solution.

    With CPU it is good to check cinebench single thread results, something like 170 is kinda minimum in current version to keep 1050Ti fed, there is not much faster CPU than 210 points on that test, so no matter what you do, CPU will be bottleneck with faster cards.

    If CPU is slower than that 170, then it still is not big problem, at times GPU just will not be working at maximum possible speed and CPU upgrade can improve the speed, but it is not a problem at all to pair i3 and gtx1080, it still is fast, some i3's are even faster with 1-2 cars i7-8700.
    It is far more complex with BeamNG than any calculator can show and those can be very misleading for BeamNG.


    PSU open the case, check model, find out how many watts it can do, then you need to find out how much current GPU uses, how much new one uses and see if new one is still within range of what PSU can do. In some cases new GPU can use less power and be faster than old one.

    I'd recommend using the https://www.bequiet.com/en/psucalculator to check how much power you need for your setup. Make sure that the wattage of your power supply is above what they tell you here. If it's not, you should buy a new one of course, and if you already have to, I'd say get one that has 100-150W of headroom for future upgrades or your next PC. And if you want to get a new power supply, I strongly recommend the bequiet Straight Power 11, Corsair RM[wattage]x and I think it was the Cooler Master V[wattage]. They're really expensive but very high quality, efficient and quiet. Also fully modular so you only have as many cables in your case as you need.
    But if the power supply you already have is enough just use it.

    Also, @fufsgfen , as the owner of a Ryzen 5 I strongly disagree with you because I have mine overclocked to 4.0Ghz with no problem whatsoever which is proven to reach the single thread performance of an i7 for exactly 200€.

    Thing is you need to overclock it and overclocked intel is much faster again.

    And much more expensive. I payed 50€ less than I would've for a 9600K, got whatever AMDs version of hyperthreading is extra and my B350 PLUS cost me 80€ as well. So fight me.

    Value is excellent in Ryzen, performance is good too, but when fastest intel overclocked faces single core limits in game, then with slower CPU one has to make compromises, but not much if one is able to overclock the chip.

    Developers are on it though, see here, CPU bottlenecks are getting help:

    Seems like this will be a looong time until i finish the build...XD
    How would you rate the ASRock Z390 Extreme4?
    (It's the cheapest motherboard with the LGA1151 and Intel 300 chipset i have found)

    How long have you been looking? That's a 160 dollar motherboard! Unless you're planning a gaming PC over 1000$ i wouldn't spend that much

    I would not put motherboard that costs under 200 to computer, tends to be bit of lottery and with current developments systems would last very long times performance wise, so longevity would be my choice of build goals. 5 years is nothing with well chosen parts (PSU and MB most importantly).

    Less features might be then one option, but cheapest is not good choice, price somewhat goes together with quality.

    I would wait for next year to see what AMD comes up with, it is good time to save bit more budget for the build too.

    One cheaper with the LGA 1151 and Intel 300 Chipset would be nice

    I want a budget-wise so, i'm not looking to spend a lot

    If 310 chipset would be enough, that would be cheaper, Z is top of the line, H or B is cheaper and if you are looking to go for budget, then AMD option is there, you might need a little overclock or then not, depending which GPU you wish to get.

    For example with gtx1050Ti, GPU limits come in sooner and even lesser CPU can feed that fully.

    For really budget build, I would think overclocked Ryzen 5, that is giving much better performance for the money, just not as high performance as best, but best is not budget solution.

    It is bit unclear to me what is your current system and do you look to buy GPU or build whole system? It could be possible to just upgrade GPU if you currently have desktop machine.

    2nd hand gtx1050Ti (or maybe even 1060) is not going to cost too much, but not knowing more details it is bit hard to tell if that would be possible upgrade for you.

    I have a decent one that I have planned for a build I'm working on myself. It's an Asus TUF H310-Plus Gaming motherboard. It has an Intel H310 chipset and an LGA 1151 socket and as of now is about $85 on PC Part Picker. It has really good features and supports DDR4 RAM 2133, 2400, and 2666.
