Buying advice: What do you need for a gaming PC?

Gaming PCs are characterised by more than enough power for current games, plenty of memory, quiet operation with optimal cooling and, of course, a chic gaming design including RGB lighting. In bestware's PC configurator, you can put together the ideal gaming PC online and configure it yourself.

In the following buying guide, we show you what you should look out for if you are planning to buy a new gaming PC. It is important that the components are well matched and deliver exactly the performance you need for your favourite games. You should also consider that, in addition to the gaming computer itself, you also need the right accessories. gaming monitors, a gaming keyboard and gaming mouse, and a gaming headset complete your setup.

Windows 11 is certainly the most widely used operating system among gamers. But Linux is also becoming more and more popular for gaming on gamer PCs. Valve has done a lot of work recently with the Steam client and the current Proton API, so that Linux gaming is also becoming interesting for standard users.

Buying a gamer PC: It all depends on the latest hardware

Basically, you should make sure to use only the latest components when building a gaming PC. At bestware, you can be sure that we offer the latest hardware as soon as it is available. Current NVIDIA GeForce RTX as well as AMD Radeon RX graphics cards offer you plenty of 3D performance for your games and guarantee you high FPS (frames per second).

This also applies to processors such as the AMD Ryzen 5, AMD Ryzen 7 and AMD Ryzen 9 as well as Intel Core Ultra 5, Intel Core Ultra 7 and Intel Core Ultra 9. This means you are well equipped in terms of performance for all current games.

How much performance you really need depends above all on the resolution in which you play. Below we give you some recommendations on which graphics cards you should choose for 1080p (Full HD), 1440p (WQHD), for gaming in 4K (UHD) or for VR games. We also give you tips on how much RAM a current gaming PC needs, how big and how fast your SSD should be, which CPU cooler is right for you and how much RAM you need for gaming.

We will show you in detail below which configurations make your gaming PC the optimal overall package.

What to look for when buying a gaming PC? Basic question: graphics card

The most important component of any PC for gamers is a powerful graphics card with modern features. The performance level you need depends on the following factors:

The higher the monitor resolution, the more GPU power is required

The higher the resolution of your monitor, the more pixels the graphics card has to calculate. While you can choose a graphics card with a particularly good price-performance ratio for a Full HD monitor, a 4K monitor or even a high-resolution VR headset often requires an expensive high-end model - at least in AAA games.

Ray tracing, DLSS and FSR: killer features for modern gaming PCs

Ray tracing provides an incredibly realistic graphics quality with physically correctly calculated light sources, such as real-looking shadows and impressive reflections on the surfaces of objects. The feature is already supported by many games and more are being added every month. There is no doubt: ray tracing is the future.

Among the titles that already take advantage of ultra-realistic graphics are Battlefield 5, CoD Modern Warfare, Cyberpunk 2077, Minecraft or Hogwarts Legacy. If ray tracing in games is an important topic for you, the top models from AMD and NVIDIA offer you a significantly higher ray tracing performance than the respective mid-range graphics cards: they have a higher number of integrated, dedicated ray tracing units.

Basically, all new AMD graphics cards (AMD Radeon RX 9000 series) and NVIDIA GPUs (NVIDIA GeForce RTX 50 series) support ray tracing - the most recent generations of graphics cards also support it, but the latest models are faster. NVIDIA performs slightly better than AMD when it comes to ray tracing in PC gaming. NVIDIA calls the dedicated ray tracing units RT cores, AMD calls them ray accelerators.

Where high graphics performance and high FPS are required - and this also applies to GPU-hungry AAA games without ray tracing support - modern graphics cards have smart solutions at their disposal that go beyond the pure raw 3D performance of the chip. These ideally ensure a higher FPS by generating and inserting additional frames, or by rendering individual frames at a lower resolution using the GPU and then upscaling them with AI, rather than rendering them completely via the GPU.
NVIDIA's current solution is called Deep Learning Super Sampling 4 (DLSS 4) with Multi Frame Generation, whereas AMD uses FidelityFX Super Resolution 4 (FSR 4). While these approaches differ in their methods, they both aim to enable smoother gaming by providing more frames per second (FPS) while maintaining high graphics quality. AI is also used in the process. Compared to older approaches such as FSR3 and FSR2, as well as DLSS3 and DLSS2, the newer approaches are clearly superior.

How much graphics memory does a gaming graphics card need?

Modern AAA game titles such as Cyberpunk 2077 and Hogwarts Legacy require a lot of graphics memory (VRAM), depending on the selected graphics details and display resolution. On a 4K monitor with the highest texture quality and ray tracing enabled, the VRAM requirement of VRAM-intensive AAA titles can quickly exceed 10–16 GB.

The high-resolution textures of your games should ideally fit completely into the VRAM, which prevents reloading jerks. In case of doubt, more graphics memory means more future-proofing, but with the predominantly 12 to 16 GB of current graphics cards you are already well equipped. The 24 GB of a GeForce RTX 5090 can only be used in exceptional cases and virtual reality gaming.

If you only play in Full HD resolution anyway and can do without high quality settings, 8 GB of graphics memory can be sufficient. The rule of thumb is: the higher the selected texture quality, display resolution and other, the more graphics memory current games occupy.

Which graphics card should you choose for your gaming PC?

At bestware you can assemble your gaming PC with different graphics cards. Here you will find a brief overview of how you can classify the graphics cards in terms of performance. Please note: If you want to gamble with maximum real-time ray tracing settings, you will need a faster graphics card even for a lower resolution and in some games you will not be able to avoid using NVIDIA's DLSS or AMD's FSR.

Please note: A graphics card from the last generation, such as a GeForce RTX 4090 or RTX 4080 or a Radeon RX 7900 XT or RX 7800 XT, can still be a good choice.

However, for the sake of clarity, the following overview only takes current models into account and lists the graphics cards in ascending order - from the entry-level solution to the unrestricted recommendation. If you also want to play with ray tracing, the requirements increase compared to the recommendations in the list and 12 to 16 GB of VRAM are mandatory.

Here, it is sometimes worth reaching for a GPU from the next higher performance class. For example, fully recommendable 4K gaming with ray tracing is only possible with NVIDIA graphics cards from a GeForce RTX 5080 upwards, while AMD's current top model, the Radeon 9070 XT, is great for WQHD resolution including ray tracing.

For high quality settings when gaming, we recommend the fastest models for the following resolution levels.

SSD ensures blazingly fast loading times in the gaming PC

Compared to conventional, mechanical hard disks, solid state disks (SSDs) operate silently and significantly faster. Here, there is no read/write arm that has to glide over several magnetic disks inside in search of data. Instead, the SSD works similarly to a USB stick or an SD memory card: a controller silently accesses flash memory cells.

The fastest mechanical hard drives achieve read and write speeds of between 250 and 300 MB/s under optimal conditions. In addition, they are much slower than an SSD in terms of access times.

When buying a gaming PC on bestware, you should make sure to choose an M.2 SSD with PCI Express connection as the primary drive.

For example, you can load game saves much faster and reload content in the game in less time when switching from one region to the next. Even starting the PC or operating system and working feel much faster with an SSD: When you switch on the computer, you are in Windows in a few seconds and clicked programmes open immediately.

At bestware you can configure your desktop gaming PC with one or more SSDs. Make sure to choose a sufficiently large drive with at least 1 TB storage capacity, because even one installation of Call of Duty Modern Warfare can take up almost 200 GB! With regard to the speed of the M.2 SSDs, you should note:

• M.2 SSDs with PCI Express 4.0 can achieve a theoretical maximum speed of up to 7000 MB/s during data transfer.
• M.2 SSDs with PCI Express 5.0 can achieve a theoretical maximum speed of up to 14000 MB/s during data transfer.
• How fast your SSD really reads and writes depends on the model you choose, the controller, the SLC cache and DRAM cache, and the memory cells

How much RAM does a gaming PC need?

For current games and otherwise normal PC use without restrictions, you should configure a gaming PC with 32 GB DDR5 memory on bestware. Gamers do not benefit from 64 GB and more; such RAM sizes are especially important for creative professionals who want to keep even high-resolution photos, images or videos in the RAM for the fastest possible access during editing. However, 16GB is almost not enough for some games.

If you want to squeeze a few more FPS out of your games, you should choose the fastest possible RAM - such as DDR5-5600 or DDR5-6000. 

If you configure your gaming computer at bestware, you will find special pre-selected DDR5 memory modules in the configurator of the online shop that perfectly fit your new gaming system.

How many watts should the power supply unit have for a gaming PC?

When buying a PC for gamers, you should always make sure you have a sufficiently powerful and, above all, high-quality power supply unit. The power supply is the key component for a stable, trouble-free gaming PC. That's why we offer you optimally processed Seasonic, Corsair or Asus power supplies in various performance classes in the bestware PC configurator. These are also characterised by high efficiency in accordance with 80 PLUS Gold, 80 PLUS Platinum, and 80 PLUS Titanium. 

How much power a gaming PC consumes depends on the components installed in it. High-end CPUs and high-end graphics cards can be quite power-hungry. The following recommendations are only rough guidelines - how many watts you really need also depends on your CPU, the amount of RAM and SSDs or the number of fans installed in your PC chassis:

• For gaming PCs with an entry-level graphics card (NVIDIA GeForce RTX 5060 Ti, AMD Radeon RX 9060 XT), we recommend a power supply with an output of 550 watts or more.
• For gaming PCs with mid-range graphics cards (NVIDIA GeForce RTX 5070, AMD Radeon RX 9070), we recommend a power supply with an output of 650 watts or more.
• For gaming PCs with high-end graphics cards (NVIDIA GeForce RTX 5070 Ti, AMD Radeon RX 9070 XT), we recommend a power supply with an output of 750 watts or more.
• For the current, absolute top models such as the NVIDIA GeForce RTX 5080 or RTX 5090 or AMD Radeon RX 7900 XTX and the most powerful CPUs currently available, you should go at least for an 1000-watt power supply.

The optimal gaming PC is characterised by first-class cooling

In order for you to be able to call up the performance of your desktop PC permanently, strong cooling of the components is required. This is especially true for high-end gaming PCs: if the graphics card or the processor get too warm, they clock down and deliver less than the performance you paid for. Many off-the-shelf PCs in particular suffer from the problem of inadequately dimensioned cooling.

At bestware, you can therefore choose yourself which ventilation options and cooling systems you want to configure. All gaming PCs that you can assemble and buy from us already have high-quality fans and CPU coolers in the basic equipment.

Which case should you choose for a gaming PC? First of all, you should consider how much space you have available for your computer: large big towers offer more space for additional fans than a much more compact midi tower or mATX tower. If you configure additional 120 mm or 140 mm fans in the case, this not only ensures better component temperatures. The additional ventilation can also ensure a very quiet gaming PC even under full load.

Finally, you should pay special attention to the CPU cooling. This is especially true when it comes to choosing a processor cooler for a powerful twelve-core or sixteen-core CPU. A high-quality CPU air cooler such as the be quiet! DarkRock 4 already delivers a lot of performance, allows moderate CPU overclocking and, above all, is durable and not susceptible to faults.

If, on the other hand, absolute top performance is required, there is no way around a high-performance compact water cooling system (AIO water cooling). Here, the size of the radiator determines the performance, among other things. Models with 240 mm, 280 mm and 360 mm radiators are common. They can dissipate even more waste heat than an air cooler and work quietly and with superior performance reserves even in overclocked gaming systems.
