Recommended Hardware for 4K Gaming Computer

Hardware We Recommend for Gaming at 4K

Designing the right system for the current scenario is a core element of our mantra at Top Flight Computers. If you don't get the right parts, it doesn't matter how much you spend on your computer...you'll be stuck with expensive hardware that doesn't work well with your situation.

4K Gaming PC Overview

This 4K Gaming PC is built around the Intel Coffee Lake Refresh platform, providing an very high amount of single-core speed, ensuring high FPS when gaming at 4K.

Games are mainly single-threaded applications, so this system is built around a high-powered Intel i7-9700K eight core CPU, making it ideal for the vast majority of 4K gaming at high settings.

System Design

This system has been configured with 8 high-speed CPU threads, 32GB of DDR4 RAM, a powerful and efficient RTX 2080 video card, and multiple storage options.

This 4K Gaming PC performs well at 4K on high settings.

Let’s Do It!


We chose the i7-9700K for its overall performance in games, and near-best single-core performance (beaten only by the i9-9900K).

While not very price-conscious, it is widely accepted as one of the best gaming CPUs on the market.

In 4K resolution, a large chunk of the processing weight shifts to the GPU, and the i7-9700K provides enough horsepower to power through most games, and properly feed data to the video card.

This provides a very stable platform for a multi-year gaming system.

Intel Core i7-9700K 8-Core Processor

System Change: If you come across a need for more clock speed, or more cores, you can easily upgrade to an i9-9900K with no need to change the system otherwise.

Please contact us if you have any other design questions or changes.


Corsair H150i PRO Liquid CPU Cooler

Due to the i7-9700K tending to run hot, we've selected a very good aftermarket closed-loop liquid cooler. Water has a higher specific heat than air does, and thus cools much better. It can hold more heat energy per volume, thus moving more heat away from the source.

Using water cooling allows you to push your CPU harder, while maintaining the same thermals, or run the CPU at the same settings, with lower noise (and still good thermals).

The higher-end liquid coolers such as the one selected above come with very long manufacturer warranties (upwards of 7 years), so the failure rate is extremely low.

System Change: If you are unsure if your cooling idea will work with this case, please contact us for further review and assistance.


We chose a high-quality Z390 series motherboard for robust performance and long-term reliability.

MSI is a very good manufacturer of motherboards, and while this motherboard is a little expensive, it provides an extremely robust long-term platform for the i7-9700K.

While we don’t have multiple video cards, this Z390 model does support multiple video cards via SLI and CrossFire.

This motherboard has excellent power delivery, a simple visual design, three PCI 3.0 slots, support for multiple M2 NVME drives, and up to 64GB of memory.

MSI MPG Z390 GAMING PRO CARBON Motherboard

System Change: Please contact us if you have a question about a potential system upgrade being compatible with your motherboard.


G.Skill Trident Z RGB 32GB DDR4-3000 Memory

We went with 32GB of Trident Z memory due to the extremely high quality of the internal chips.

This setup will give the user plenty of room for open applications.

System Change: The motherboard selected supports a maximum of 64GB of memory, in a 4x16GB array. Needing more than 64GB of memory would require a motherboard change as well as a CPU change.

Please contact us if you have any other design questions or changes.


Samsung 970 Evo 500GB M.2-2280 SSD

The SSD and HDD were chosen for their high capacity, relatively low cost, and high reliability.

Western Digital Black 2TB HDD

System Change: If you come across a need for more storage, you can easily upgrade to a bigger SSD or HDD, with no need to change the system otherwise.

Please contact us if you have any other design questions or changes.


EVGA RTX 2080 8GB XC ULTRA GAMING Video Card

The video card was chosen for its large memory capacity, ample CUDA cores, RT cores, Tensor cores and support for 4K resolution.

This video card has a very capable aftermarket cooling solution, and will prevent any sort of thermal throttling from taking place.

Let’s Do It!

System Change: If you come across a need for more graphical horsepower, you can easily upgrade your video card with no need to change the system otherwise.

Contact us if you have any other design questions or changes.


The case was chosen for its high build quality, room for plenty of high-end hardware, and incredible amount of cooling potential.

Phanteks Enthoo Pro M Tempered Glass (Black/White) Mid Tower Case

System Change: Reasons for changing the case can be very hard to pin point.

If you have a question about the compatibility of the case selected with an upgrade, please contact us.


Corsair ML120 Pro RGB Fan

We have selected a set of high-quality pressure-optimized fans to ensure sufficient airflow in the case to keep the system stable under heavy load.

Having high quality fans also means less noise, even when the fans are spinning at high RPM.


The power supply was chosen for its high build quality, ample power capacity, and respectable thermal efficiency.

A higher wattage PSU than necessary will also prolong the life of the unit, as it isn't being operated near peak load.

Using a high quality power supply means better power delivery, and cleaner power. Messy power can result in a system failure, corruption of data, or even a hardware crash.

EVGA SuperNOVA P2 850W Fully-Modular Power Supply

System Change: If you decide to upgrade any single major draw of power, you do not need to change the power supply. If you change multiple draws of power, you may need to upgrade the wattage on the power supply.

Please contact us if you have any other design questions or changes.
