You want to put together your next gaming PC yourself, but feel overwhelmed by the huge selection of components? Which processor fits which motherboard? Which graphics card is required for which resolution? So that you do not lose the overview, GIGA editor Daniel introduces several configurations and explains what else you have to pay attention to when putting together your own gaming computer.

Almost every year, major hardware manufacturers release new processors, graphics cards and more. So far, Intel has been the top dog when it comes to processors. In the meantime, AMD has become a serious competitor – and of course this primarily benefits consumers. Such a large selection of PC hardware makes 2020 the ideal year to put together your own gaming PC.

So that you don't have to search for the optimal hardware yourself, we present a total of four configurations. Starting with the Entry-level PC for about 800 euros about one Mini Gaming PC up to High-end Monster For 3,000 euros there is guaranteed something for everyone. In addition, we take a closer look at the individual components and explain to you what you should definitely look out for before buying and why it is worth assembling your own gaming PC.

Note: The prices listed here are rounded and can change at any time. In addition, no operating system is included. (As of February 25, 2020)

The heart of the entry-level PC is next to that AMD Ryzen-3600 processor the ASRock Radeon RX 5700 Challenger D 8G OC, According to the manufacturer, the graphics card is primarily designed for gaming in Full HD, but it also delivers respectable frame numbers in WQHD. With this configuration, graphically demanding games should run at maximum settings with 60 FPS and more without any problems. With less demanding Esports titles, on the other hand, there is more FPS in it.

Depending on how tight your budget is, that would be Sapphire Radeon RX 5600 XT Pulse a something cheaper alternative with almost identical performance, but only 6 GB VRAM. The mainboard requires one BIOS flash, because Ryzen 3000 processors are not natively supported. Here it is advisable to take a look at the manual beforehand. The included cooler for the CPU is more than sufficient, as long as you don't want to overclock your processor.

You wonder what the BIOS is anyway? In our video we explain exactly that and more:

As the name suggests, this configuration is a real all-rounder. The gaming PC is powered by AMD Ryzen 7 3700X, It is an eight-core CPU that shines with its outstanding multicore performance. There is also a Gigabyte RTX 2070 Super Windforce OC in the all-rounder PC. This means you have more than enough power to enjoy all games in WQHD resolution and 60 FPS and more. If necessary, you can also use the CPU overclockto really get the maximum out of your PC.

Do you want the crème de la crème when it comes to gaming hardware? Then you come to the Asus RTX 2080 Ti Gaming OC not over. Incidentally, this accounts for almost half of the total price of our high-end monster. There is currently no other graphics card with so much power, except the Titan RTX. That alone would make up almost the entire budget of this configuration.

The computer is supplemented by the AMD Ryzen 9 3900X with a total of 12 cores. In particular, when editing video or streaming, you benefit from so many cores. Finally there are still 32 GB RAM and a total of 1.5 TB NVMe storage in the high-end configuration. Conventional hard disks have been dispensed with because SSDs offer much higher read and write rates, work silently and take up significantly less space.

  • High overclocking potential thanks to water cooling
  • Ideal for 4K gaming, streaming, video editing and more
  • Mainboard with built-in WIFI and Bluetooth


Mini gaming PC: Minimum size with maximum performance

Note: The prices listed here are rounded and can change at any time. In addition, no operating system is included. (As of February 25, 2020)

The heart of this minimalist-looking computer is clearly the case. More specifically, that LOUQE Ghost S1that just with one Volume of 8.2 liters comes along. For comparison: the interior of the Phantek's Enthoo Evolv X our high-end monster is a whopping 65 liters! The rest of the hardware is also perfectly coordinated, since every millimeter really counts on such a compact gaming PC. If necessary, the housing can be due to its modular design still be expanded to provide space for water cooling, for example.

By the built EVGA RTX 2070 Super XC Gaming and the AMD Ryzen 5 3600 Despite its small size, this machine offers more than enough power to play all current games in the best graphics. This mini PC is therefore ideal for purists or those of you who would like to take your computer with you when you travel or the next LAN party.


  • Reduced look
  • A lot of performance in a small space
  • Modular housing
  • Computer can be transported easily
  • Mainboard with built-in WIFI and Bluetooth


  • Relatively high price
  • Complicated assembly
  • Low overclocking potential due to compact cooler

Assemble gaming PC 2020: how the components were selected

If you put together a gaming PC, there are almost endless combinations when it comes to hardware. First of all, this is a big advantage. On the other hand, such a diverse selection can be overwhelming, especially since everyone Components precisely matched to each other have to be. For this reason, care was taken in each of the systems presented here that all components such as the processor, the mainboard or the graphics card fit together perfectly.

Of course, none of the configurations is carved in stone and individual components can be replaced by others if necessary. We mainly refer to our own experiences and have placed special emphasis on qualitative hardware which is also future-proof.

Assemble gaming PC: what should I pay attention to?

The price

If you put together your own gaming PC, the price of course depends entirely on you. You should always ask yourself the following question: What are the requirements for my gaming PC? Do you only want to gamble with it or should it also be used for streaming or for other computing-intensive software? Then you should be yours budget establish and about a third of it for the graphics card plan on.

Another tip would be that you don't save at the wrong end, especially with less noticed components such as the mainboard or the power supply, and also opt for high-quality components here. You don't want to risk that all of your hardware is sizzled by a short circuit in the power supply, for example.

Finally, it is up to you to decide where to buy your hardware. In our case, we tried to limit ourselves to one dealer if possible. This may not always be the cheapest option, but it makes a lot more sense in terms of warranty and support.

The components

Processor: Intel vs. AMD

For a long time, Intel was the undisputed number one in terms of CPUs. Things are different now. With the introduction of the Ryzen processors, AMD has made a huge leap in performance and has become the favorite of numerous hardware fans. Nevertheless, both processors still have their right to exist. The most important thing when choosing a processor is the scope of application as well as that Price-performance ratio,

In the latter, AMD is clearly ahead of the game at the moment. Coupled with the longer-term backward compatibility their mainboards and the excellent ones Multicore Performance they are an excellent choice. Especially if you use your computer for gaming purposes other than gaming, such as video editing.

In contrast, the Intel processors are unbeaten Single core performance, Since the majority of current games benefit from this, Intel currently tops many of the benchmark lists in this area. However, the manufacturer can be compensated for this bonus accordingly.

Graphics Card: Nvidia vs. AMD

When choosing a suitable graphics card, you are once again spoiled for choice. The selection is then made even more difficult by the fact that you are using one of your monitors Variable refresh rate (VRR) want to benefit. With freesync from AMD and G-Sync from Nvidia, both manufacturers have said technology that synchronizes the refresh rate of your monitor with your respective graphics card.

This is to ensure the smoothest possible gaming experience without tearing or other artifacts. In the meantime, even Nvidia GPUs can benefit from Freesync monitors, which could make it easier to make a purchase decision.

Ultimately, it depends on how much power you actually need. Especially in the lower price segment up to the middle class, AMD usually offers the better price-performance ratio. However, if you want the absolute maximum in performance, then you cannot avoid Nvidia at the moment. In addition, features like raytracing or DLSS so far only reserved for Nvidia cards. All of these points should be considered before buying.

Watch this video and find out exactly what ray tracing is and how it is used:

RAM: What memory size and frequency?

Ideally, your gaming PC has at least 16 GB random access memorySo that you’re armed for the next few years. If you use other computing-intensive applications besides gaming, you can of course also choose 32 GB or even 64 GB RAM. In addition to the memory size, RAM also differs in clock speed (e.g. 3,600 MHz) and the timings (e.g. CL14 or CL16).

Roughly speaking, these determine how efficiently the main memory works in your PC at the end. Basically, Ryzen CPUs benefit significantly more from an increased clock frequency than Intel processors do. It is much more important which frequencies your motherboard actually supports. Most of the time, it's also a lot smarter to be Better spend money on a stronger processor or a more powerful graphics card to invest than in overpriced RAM.

Hard drives: The main differences explained

Basically you have the choice between a conventional hard drive Hard Drive Disk (HDD) or one Solid State Disk (SSD), The former are still the cheaper option and are therefore ideal as a medium for mass storage. The big disadvantage, however, is their minor Read and write rate, SSDs work much faster and should therefore not be missing in any modern PC. However, this storage costs significantly more and has a shorter lifespan due to its design.

So far, SSDs were considered 2.5-inchFormat is still the standard, but the space-saving version is gradually becoming established in M.2-Format. It should be noted, however, that M.2 hard drives are both available via the SATAconnection as well as about the PCIe interface (NVMe) can be connected. The latter is definitely recommended, since the data transfer rates are significantly faster and long loading times in games are a thing of the past. For comparison, the maximum read / write rates of different hard drives:

  • HDD with 7,200 rpm: about 100 MB / s
  • SATA SSD: about 500 MB / s
  • NVMe SSD: up to 3,500 MB / s

Motherboard, case and co.

As far as the rest of the hardware is concerned, the main ones are Dimensions of the individual components urgent to note, Do the CPU cooler and graphics card fit in the case? Is the RAM low enough to fit under or next to the CPU cooler? For this, the dimensions of the respective components should simply be compared with one another. The manufacturer's pages usually contain detailed dimensions that make this work easier for you.

Is the mainboard compatible with the processor? The first thing that matters is whether you are installing an AMD processor or an Intel processor. Both use different standards or bases. In case of AMD would that currently be the AM4 socket, Intel, on the other hand, uses the for current core processors 1151 socket, In addition there is inside the base different serieswhich in turn fit the respective processor generations.

Intel CPUs 8th and 9th generation use, for example 300 series, for example Z390. The counterpart at Ryzen-3000 CPUs of AMD would be accordingly 500 Series, so an X570 motherboard. In many cases, older motherboards with the latest CPUs will also work if the BIOS has been updated beforehand.

After all, your should power adapter about enough power to supply your PC with enough power. That is at least as important efficiency of the power supply, which is specified in bronze, silver, gold, platinum or even titanium. Usually it is enough 80+ gold certified power supply between 550 and 750 watts more than out. All these factors and more have of course been taken into account in our configurations, so that no bad surprise awaits you afterwards.
