It is quite rare that a new CPU generation hits around the same time as a new GPU generation. We’re of course talking about AMD’s Ryzen 5000 and Nvidia’s RTX 3000 series which both push the boundaries of gaming performance to never before seen levels. The leaps in both processor and graphics performance warrant a great time to build a PC for the next 3 years+ depending on the specs you’ll be getting. Today we will be recommending a high end build around the $2000 price point which packs the highest levels of gaming performance at the end of 2020.

You heard it right, this build can achieve an average of 30 to 35% better FPS than the previous best $2000 gaming build which featured a Ryzen 7 3700X and an RTX 2080Ti; that’s a huge leap at the same price point and consumers like you and me can now enjoy it. The new Ryzen 7 5800X series is an enthusiast’s dream with gaming performance levels exceeding even the Core i9 10900K. These gains on the Ryzen 5000 series come from the huge 19% uplift in IPC, single core performance and core to core latency improvements. In short terms, the 5800X is a beast that sets a new standard in gaming performance.

On the graphics side, we got the RTX 3080 which is the newest effort from Nvidia to push the boundaries of high resolution and high refresh rate gaming performance. With an overall FPS uplift of around 30% above the outgoing RTX 2080Ti model which was the previous top performing single GPU on the market, the RTX 3080 establishes itself as one of the most thought after GPUs at its $700 launch price.

The Ryzen 7 5800X and the RTX 3080 are the highlights of this build but we’re going to follow up with the surrounding components in order to offer you a strong build in all other areas such as storage, cooling and memory capacity. Here’s the specs needed for the system:

CPU: Ryzen 7 5800X

Ryzen 7 5800X

AMD used their October 8th presentation to give us a rather detailed look at their Ryzen 5000 portfolio with the Ryzen 7 5800X launched as the single 8 core / 16 thread model and available on November 5th on shelves worldwide. Their performance improvements surprised everyone and thanks to the architecture overhaul, gaming FPS is a great advantage on the Ryzen CPUs which now are marketed as the best gaming CPUs out there with a 5% or higher margin when compared to competing Intel CPUs. This is a great achievement because gaming performance was still lagging behind the Intel CPUs for the past three Ryzen generations.

Not anymore though. Its safe to say consumers are warmly welcoming this gaming performance uplift with the new Ryzen 5000 series. The Ryzen 7 5800X for example welcomes a 25% average advantage over the outgoing Ryzen 3000 XT models which happened due to the 19% IPC performance uplift and latency optimizations; such a leap in one generation just for gaming performance is impressive and we foresee a very high demand for the new CPUs.

In this build, we still could’ve used a last generation CPU such as the Ryzen 7 3700X and the price would’ve been around $150 cheaper but if we’re going to build a highly capable build that can demolish any resolution at high refresh rates, then there’s no better pairing than that of the Ryzen 7 5800X and RTX 3080 thanks to their stunning performance and good performance per dollar. We’re not going to say this build is affordable for everyone but instead, we’re going to say that bleeding-edge performance has gotten much cheaper with these two new generations of high-performance processors and graphics cards.

CPU Cooler: Dark Rock Pro 4

The Ryzen 7 5800X keeps the 105W TDP of his predecessor, the Ryzen 7 3800X and thus, is as easy to cool. All the CPU coolers that did a great job cooling the latter will up to the task with the 5800X. For a $2000 build that’s aimed at the enthusiast gamer we’d like to recommend one of the best air coolers on the market. The Dark Rock Pro 4 is a dual tower air cooler built using beQuiet!’s solid mantra of “no compromise silence and performance”. You can expect silent utilization during any load and ample rooms for overclocking if you are tweak-happy with the processor.

The heat sink consists of a huge dual tower design with seven 6 mm heat pipes while using 2 x SilentWing fans, one 135 mm and one 120mm, that are virtually inaudible during both idle and load environments. The great combination of performance, quality, value and design makes the Dark Rock Pro 4 an exception offering at its $90 retail price. Mounting this huge cooler is made easy by the simple instructions and the ample room you have in the Lian Li LANCOOL II-X case that we’re featuring in this build.

Motherboard: ASUS TUF Gaming X570-Plus (WiFI)


The gamer inside you will not need the extensive extra features of a very high-end X570 motherboard and this is why the ASUS TUF Gaming X570-Plus Wi-Fi is such a great fit for this gaming build. Its VRM design is shared with the much more expensive Maximum XI Hero motherboard and at this price point, its one of the most capable motherboards that can run any Ryzen 5000 chip even with heavy overclocking thanks to its strong hardware features.

With a stellar BIOS layout and frequent updates, you’ll feel like the X570 will leave nothing to be desired. Features include the PCIe 4.0 standard which will aid our RTX 3080 and storage device to stretch their wings, 14 Phase VRM, 128GB 4400MHz support through the 4 RAM slots, 2x M.2 slots one of which is passively cooled and a great Realtek ALC S1200A Audio CODEC. The TUF is also pretty generous with its I/O; the 3x USB 3.2 Gen 2 (1 x Type-C) + 4x USB 3.2 Gen 1 ports and 8x SATA 6Gb/s ports are most likely enough for any gaming enthusiast or streamer out there. For new AMD builders getting ready for their first gaming machine, the TUF Gaming X570-Plus WiFi is a great option that doesn’t break the bank and offers all the key features and configurability of AMD’s AM4 platform.

Memory: G.Skill Ripjaws V 32 GB (2 x 16 GB) DDR4-3600 CL16

G.SKILL Ripjaws V 16GB 3200MHz CL16

With DDR4 slowly approaching the end of its life and thanks to the high level of competition in the memory market, we can afford to splurge towards the 32 GB of RAM. Many would argue that 16 GB is enough for a gaming build and that is very true with mainstream and high end builds; you are not going to exceed 10-12 GB of memory usage in any of the latest titles but you are going to cut it close with the 16 GB. If you’re one of those PC users that like to keep open tons of applications or browser tabs or even someone who would like to use their PC as a rendering and editing machine then 16 GB would induce a bottleneck into this great gaming build and we would like to avoid it at all costs. It’s very cheap to do so with the extra 16 GB of high-performance system memory.

This build is also crafted to last you for many years and 32 GB of RAM will surely take care of your needs for its full lifetime. The low 8.889 memory latency of this G.Skill DDR4-3600 CL16 RAM kit will also aid overall performance and snappiness of your system and will pair well with the Ryzen 7 5800X. If you like tweaking then you will be able to tune this memory kit’s clocks and CAS latency to even higher performance levels in order to bring even more improvements to the Infinity Fabric speed of the Ryzen CPU. The Dual Channel (2 sticks) nature of this RAM kit is also mandatory in order to benefit from the full bandwidth of the AM4 platform. We like this kit very much thanks to its performance and affordability but you can also check our articles on different RAM kits if you’d like more options to choose from at different price points.


Its mandatory that such a fast gaming system will need to run on a solid piece of storage in order for you to enjoy lag free application opening, installations and game loading. We will be going with a storage combination between a very fast PCIe 4.0 NVME device in the form of the Sabrent Rocket 4.0 500 GB and a 1 TB Crucial P1 M.2 in order to have the OS and most frequently used applications on the main Sabrent device while the more rarely used apps and general file storage can sit on the Crucial P1. This way, we are ensuring great speeds and enough capacity without breaking the bank. If these two devices don’t offer enough capacity for your needs then feel free to upgrade to bigger M.2 sizes.

Storage 1: Sabrent Rocket 4.0 500 GB M.2-2280 NVME

Sabrent Rocket 4 500 GB

The OS drive will be powered by the Sabrent Rocket 4.0, a rather new drive that uses the Phison E12s controller, a 96 layer TLC flash by Micron and the new PCIe 4.0 interface in order to ensure snappiness and a performance edge to your transfers and file access. The DRAM chip is there to offer a massive performance uplift for random writes; it brings a very fast temporary storage for the drive’s internal mapping tables so that it doesn’t slow down during sustained load. The device is also very hard to throttle because even though it heats up, the slow downs are well masked and avoided by the inclusion of a copper foil over the M.2 drive that acts as a heat spreader thus handling the extra heat. Sabrent is claiming this foil helps the drive run at max speed 4 times longer than without it.

Storage 2: Crucial P1 1 TB M.2-2280 NVME

Crucial P1 1TB NVMe SSD

We will also be using a very popular M.2 drive that may be not as fast as the Sabrent but it offers a very good value for capacity. The Crucial P1 provides excellent value for people that need very fast and cheap storage. The only occasion where this drive slows down is when you’re doing transfers bigger than 50 GB at a time because of its limited QLC cache. That will happen almost never in everyday use and besides that, the drive is lightning fast; it features speeds of up to 2,000 MB/s read and 1,700MB/s write – much faster than your usual SATA SSD. If you are in need of even more capacity on your system then a 2 TB version of the Crucial is also available at a very competitive price.

Graphics Card: RTX 3080


The RTX 3080 delivers very impressive performance especially when it comes to higher resolutions like 4K. The generational improvement over the RTX 2080 Super and top-end RTX 2080 Ti is very welcome for people that want to experience more with more graphically intensive games and Ray Tracing. Real-time ray tracing is running smoothly on a single RTX 3080 and what’s more impressive is that the card is around 25% better in rasterization when compared to the RTX 2080Ti while being a lot cheaper, at $699 launching price. Third-party cards may retail for a slightly more expensive price though.

This card is an excellent performer in any of the new Triple-A, VR and eSports titles and does it at a respectable but slightly high TDP of 320W – this is why we’ll be including a great PSU to go with the build; we want to ensure your system and gaming experience won’t be affected by any spikes in power consumption. Nvidia has set the bar very high for AMD to catch up with their new RX 6000 series but until then, the RTX 3080 is the card to have for gamers if you can get one. With its 10 GB of GDDR6X memory, any current title should be able to run at max settings without the worry of going over the max memory.

Thanks to the Ryzen 7 5800X in the system, the RTX 3080 will be able to spread its wings and perform very well not only in 4K but also in 1440p or even 1080p high refresh rate games where previously, many CPUs would bottleneck such a high performing graphics card.


Lian Li Lancool 2 II-X

The Lancool II belongs to Lian Li’s mainstream lineup but there are lots of impressive features about it. The chassis is designed from scratch in order to ensure easy building, cable management and maintenance, the aesthetics are very nice with premium looks and the thermal characteristics are great with the additional included fans in our build. Lian Li has managed to pack a lot from their more expensive lineups in a design and feature set that doesn’t look like its compromising much. They have taken every popular priority that consumers are asking for in a high-end case and stripped everything else that is rarely needed. For the $90 retail price, the case is definitely fit to home a high end build such as the one we’re designing.

This ATX case also comes with a lot of extra features that are cost options. Hot swappable drive bays, USB Type C I/O and a vertical GPU mount are some of them with a ton of additional accessories and customization possible. The stock configuration is easy to build in thanks to its dual-hinge doors, many tie-down points and PSU shroud. The cooling for the case is not great when using just the three included fans and that is why we’re going to use a third party pack of Cooler Master SickleFlow 62 CFM 120 mm fans. You can do a setup with intake fans at the bottom and front and exhaust fans at the back and top in order to ensure equal pressure and sufficient airflow for your components. The additional three fans are not mandatory but you’ll obtain a much cooler and silent system if you decide the $49 on the additional fans.

Ultimately, we are big fans of how Lian Li has built the Lancool II-X as a fantastic blend between aesthetics, price and performance and that is why we’re sure it will go very well with the rest of the components in this build.

Power Supply: EVGA SuperNOVA G1+ 750 W 80+

EVGA SuperNOVA 750 G1

The total max power draw of this Ryzen 7 5800X gaming PC build sits around 450 to 550W during a 100% CPU and GPU utilization under render loads. That is a very rare occurrence but we’ve prepared the build for that with the EVGA SuperNOVA G1+ which is a very high tier PSU from a world class trusted brand. The PSU can easily handle any power swings during the diverse loads you’re going to put the system through and will do it silently and stress-free.

Being a fully modular power supply, the G1+ will allow you to just use the cables that you really need for this build. Building this way you’re going to leave the case uncluttered and ensure a more easy way to do maintenance or upgrades on your full build; storage, RAM swaps or regular cleaning has never been easier with such good cables and case layout. Their cables also have a premium bend feel to them and thanks to their dark sleeving, you can arrange them inside the Lian Li case in order to obtain a very clean look. The RTX 3080 graphics card comes with a bundled 12 pin power connector that you can use for the PCIe cables but EVGA also takes care of this with their own version of the 12 pin connector. If your G1+ has been manufactured before the RTX 3000 series then EVGA will send you the added 12 pin connector for free; this is proof that EVGA cares about the latest needs for their customers.

The G1+ ranks S tier (the highest tier) in popular PSU ranking lists for its excellent protections against surges and excellent build quality; at the $120 price point, we’re finding the G1+ perfect for this enthusiast gaming build and any upgrades that you may be inclined to add in the future.

Bottom Line

Let’s focus a little on the price you’ll be paying for this build and the performance you are extracting from it. Less than 1 month ago, $2000 would have got you a Ryzen 7 3700X & RTX 2080Ti PC which indeed offered a great amount of performance but now, with the Ryzen 7 5800X & RTX 3080 overall performance at this price point is an estimated 30 to 35% better; this is a huge leap in value for money in just one CPU & GPU generation and its why we’re so excited for this build. The most amount of money in this build is going towards the CPU & GPU which amounts to ~$1150; before this, the 3700X + RTX 2080Ti would amount to a whopping ~$1500. The $300 saved from past generation’s components to the 5800X + RTX 3080 was used to spec the build with more high-end additional components such as the X570 motherboard, beQuiet! Dark Rock Pro 4 air cooler and greater storage performance.

The build offers class-leading gaming performance at any resolution and refresh rate. If you are looking for a monitor to pair this build with, our colleagues have drafted a list of the best monitors for such a Ryzen 7 5800X + RTX 3080 build. We are thrilled to recommend this build as the best $2000 gaming PC that you’ll be able to build at the end of 2020 and if you have any additional questions, we’re happy to answer in the comment section below; the FAQ can also help you with more general questions.
