How to Build an RTX 4080 Gaming PC – ft. Nvidia Founders Edition!

RTX 4080 Founders Build Feature


After the successful release of RTX 4090, Nvidia have followed up their first 4000 series graphics card with a slightly lower priced RTX 4080, a card that looks to dominate the 4K gaming market.

The RTX 4080 is just one of many new components to launch recently, making now a better time than ever to build a high-end gaming PC build. But just how well does the RTX 4080, and which parts should you pair up with Nvidia’s budding new 4K titan?

We’ve managed to get a few RTX 4080 designs through our doors, running exhaustive testing on each of our units. This has given the data to talk through the RTX 4080’s performance, and evaluate exactly which components are best paired up with Nvidia’s newest GPU.

Main Components

4080 Founders Edition with Box

GPU: Nvidia RTX 4080 Founders Edition

Let’s start things off by looking at the main attraction, the brand-new Nvidia RTX 4080 Founders Edition! We’ve been testing Nvidia’s latest 4000 series GPU ever since it arrived at our offices, looking extensively at how well it matches up to the 4090, and last-gen 3000 series cards.

Key Facts: Base Clock: 2.2GHz // Boost Clock: 2.5GHz // CUDA Cores: 9728 // TDP: 320W // RT Cores: 76

The 4080 is an impressive card that blows the last-gen GPUs out the water when it comes to performance, and once paired with DLSS 3.0, it becomes one of the best gaming experiences money can buy. Unsurprisingly, the performance of the 4080 is weaker than the 4090, but the reduced price makes it a more accessible option.

Whilst the price will still be too steep for most gamers, the 4080 is a step in the right direction for the latest generation to compete with the price of high-end 3000 series cards such as the 3090 and 3090Ti. We will be providing more details on the performance of this card in the benchmark section later on, but be sure to check out our full reviews of the RTX 4080 graphics cards for a more detailed look at performance and the latest Ada Lovelace GPU architecture.

3070 Suprim Build - i7 12700K

CPU: Intel Core i7 13700K

To complement the RTX 4080, we’d recommend picking up one of Intel’s latest CPUs, the Core i7 13700K. You may be wondering why we decided to pick the i7 instead of the more powerful i9? To put it simply, the i7 has everything we need performance-wise, and will save us a few pennies in the process. With the high-performance parts in this build, the price can easily add up, making it necessary to reduce costs where possible.

Key Facts: Base Clock Speed: 3.4GHz // Boost Clock Speed: 5.4GHz // Core Count: 16 // Thread Count: 24

We were extremely impressed with the performance of all the Intel 13th gen processors, especially when compared to the previous generation and AMD’s new Ryzen 7000 options. The Core i7 13700K is arguably the best when it comes to price-to-performance out of the new range of CPUs, offering similar results to the Core i9 12900K. In fact, the 16 cores and 24 threads in the new i7 is the same amount as the last-gen i9, and possesses a greater boost clock speed of 5.4GHz.

If you’re looking to learn more about this CPU,we’ve covered all the details of the Intel Core i7 13700K in our full review.

CPU Cooler: DeepCool LS720

To keep the CPU in this system nice and cool, we’ve picked up the DeepCool LS720. Given the power of the components in this build, there Is a fair bit of heat to need to counter. A large, efficient cooler is the perfect way to counteract this, with DeepCool’s LS720 a top choice. With a 360mm radiator that comes with 3 fans included, the cooler’s design has been revised to provide improved cooling and noise-reduction. For example, the included water pump is on its 4th iteration, with the latest version containing improved coolant flow, a more powerful motor, and a thick copper base for a better CPU connection.

Key Facts: Radiator Size: 360mm // Included Fans: 3 // RGB: Yes

But performance is not the only quality that the LS720 will add to this build, as there is a lot of RGB incorporated into the design. Lighting can be found on each of the included fans, as well as a healthy amount on the border of the radiator pump. The pump includes a rotating plate that can be customised to project a logo of your choice, which adds a nice personal touch to any build.

ASUS TUF Gaming Z790 Whole Motherboard

Motherboard: ASUS TUF Z790-Plus WiFi D4

Moving onto the motherboard of choice for this build, the ASUS TUF Z790-Plus WiFi D4 is the ideal partner for our Core i7 CPU. Z790 motherboards have been specifically designed for Intel’s 13th gen, making them the only ‘easy to recommend’ companion for our high-end CPU of choice. We’ve looked at a number of the latest Z790 motherboards previously, and found this to be one of the top designs on balance.

Key Facts: Form Factor: ATX // Built-in IO Shield: Yes // Max Memory: 128GB

One of the main reasons for this selection is due to the sheer amount of connectivity options available. ASUS have packed a lot into this ATX board, including 8 USB ports, 4 M.2 SSD slots, and PCIe 5.0 support for the latest GPUs. All of these connectivity options makes this board a great choice for those with lots of peripherals in their setup, whilst leaving space for future component upgrades too.
