If you’ve been eyeing on building a brand new PC with the Radeon RX 7800 XT, you’ve made a wise choice. It’s an incredibly fast GPU for 1440p gaming and at an manufacturer’s suggested retail price of $500, it is one of the best value GPUs.
In this guide I will be suggesting a value-oriented build and a high-end build.
My goal was to build the fastest gaming PCs featuring the RX 7800 XT within a $1200 and $1900 budget respectively and making sure that both of them are on the latest platforms with top-notch parts for today with great upgrade paths – fast today, fast tomorrow.
Best Value RX 7800 XT PC Build
- CPU – AMD Ryzen 5 7600
- Motherboard – ASRock B650M Pro RS WiFi
- RAM – G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL32
- CPU Cooler – Stock Cooler
- SSD – Western Digital Black SN850X 1 TB
- Graphics Card – Gigabyte GAMING OC Radeon RX 7800 XT
- Power Supply – MSI MAG A850GL
- PC Case – Phanteks Eclipse G360A
The RX 7800 XT stands for flagship performance at a midrange price. This budget build is true to the spirit of the 7800 XT where every component offers great bang for the buck performance.
Starting with the graphics card itself, I chose the Gigabyte GAMING OC Radeon RX 7800 XT. It is one of the most affordable variants of the 7800 XT right at the manufacturer’s suggested retail price. It has a triple-fan configuration with sub 70-degree Celsius temperatures and a classy gun-metal body. Gigabyte has absolutely nailed the design of this card and managed to keep the overall size close to a dual-slot card.
The RX 7800 XT needs a powerful companion to run all the latest AAA games in 1440p at maximum settings. On the budget side of things, one of the best CPUs for the 7800 XT is AMD’s own Ryzen 5 7600.
The 7600 should not be underestimated whatsoever. It’s a powerful 6-core 12-thread CPU with a 65-watt TDP. You can max out games and other apps on this chip, and all it needs to cool itself is the included stock cooler. The single-threaded performance of Zen 4 CPUs has improved so much that the 7600 can keep up with a Ryzen 7 5800X3D and a Core i9 12900K in games, all the while consuming half the power of both of them.
You could also go for the Ryzen 5 7500F if you can find it cheaper for this build as it is equal to the 7600, except that it doesn’t have an iGPU, which is fine if you’re already going to use a dedicated GPU. I was initially worried that AM5 as a platform is much more expensive and that it is crucial to save as much money as possible. Thankfully, motherboards have become really affordable and it’s easy to get a top-notch board for less.
For this build, I went with the ASRock B650M Pro RS WiFi as it fits our needs while being cheap. It’s not a particularly special motherboard in any way, but it is a rock solid board for anyone building an AM5 PC on a budget. It has a decent amount of USB ports, WiFi, Bluetooth, and 4 RAM slots – spot on coverage of all the bare necessities. The VRM is also a decently powerful 8-phase config that will support up to a Ryzen 9 7950X at stock speeds so it should have absolutely no issues with an overclocked Ryzen 5 7600.
RAM support on the Pro RS is also great and ASRock generally has better RAM support than many other motherboard vendors since it can support up to 7200 MT/s RAM, but RAM that fast is too expensive and not to mention, has loose timings.
For the RAM, I went with the G.Skill Flare X5 32 GB kit – a solid choice that I’m surprised isn’t being picked up by more PC builders. It comes with 2 16 GB sticks clocked at 6000 MT/s with a CAS latency of 32 nanoseconds – this may very well be one of the best RAM kits under $100.
For a fast and snappy SSD, I chose the Western Digital Black SN850X. It’s the fastest gen 4 SSD without a DRAM cache which is perfect for saving some money while still getting a flagship experience.
For the casing, all of these components will go inside the Phanteks Eclipse G360A. Although I have been overly recommending the Montech AIR 903 MAX, I do it mainly for maximizing airflow. The Phanteks Eclipse G360A takes a more nuanced and balanced approach as a PC case. It comes pre-installed with 3 120 mm fans and needs a third exhaust fan to be added separately which honestly does feel a bit annoying. However, if you take away that little annoyance, the G360A offers much cleaner cable management at the back and a slightly better build quality. There are a lot of good cases under the $100 price, but few are truly amazing like the G360A.
Finally, to power this entire PC, it needs a high quality power supply that doesn’t break the bank. I went with the MSI MAG A850GL which is one of the best PSUs under $100.
It has everything: it is an 80+ Gold efficient PSU that can provide 850 watts of power continuously, supports the latest ATX 3.0 standard, and can power the latest PCIe gen 5 GPUs. In short, it’s the most affordable PSU that can fully power even the RTX 4090, and that in itself is the reason why the MSI MAG A850GL is the perfect PSU for this PC.
In conclusion, the Ryzen 5 7600 and RX 7800 XT make a great team! For a budget of $1200, this gaming PC can play any game you want at 1440p maxed out settings at high frame rates. This setup is powerful and well-balanced with a great upgrade path for future components as well.
Best High-End RX 7800 XT PC Build
- CPU – AMD Ryzen 7 7800X3D
- Motherboard – ASRock X670E Steel Legend
- RAM – TEAMGROUP T-Force Delta RGB 32 GB (2 x 16 GB) DDR5-6000 CL30
- CPU Cooler – ARCTIC Liquid Freezer III A-RGB
- SSD – Samsung 980 Pro 2 TB
- Graphics Card – Sapphire NITRO+ Radeon RX 7800 XT
- Power Supply – Corsair RM850e (2023)
- PC Case – Lian Li LANCOOL III
The RX 7800 XT offers gaming performance that’s neck-and-neck against the RX 6900 XT and RTX 3090. It democratized flagship 1440p gaming performance at more than half the price of those GPUs.
For this PC build the star of the show is the Sapphire NITRO+ which is the best variant of the Radeon RX 7800 XT.
It is one of the pricier variants of the 7800 XT, but it is completely deserving of its asking price. It is over-built from top to bottom – the entire PCB is covered with high-capacity VRMs and protective fuses that prevent any short circuits from damaging the GPU. Unlike most 7800 XTs, this is a true triple-slot graphics card that takes full advantage of its massive size.
The triple-fan configuration is so good that it can keep the GPU under 50 degrees Celsius in almost all of the most demanding AAA titles at 1440p at the maximum settings. The rest of the design is also beautiful; it’s got a shiny silver body with a slick RGB strip going across the entire card that can be controlled through software.
An over-engineered masterpiece.
Pairing the RX 7800 XT is a CPU that needs no introduction; I went with the Ryzen 7 7800X3D simply because it’s the best gaming CPU and nothing else even comes close to it. The 7800X3D is an 8-core 16-threaded CPU with a massive 96 MB L3 cache and will have no trouble playing any of the latest AAA titles for a very long time. I guess the only complaint, if you even want to call it that, is that it’s a slightly unbalanced CPU. It is the world’s fastest CPU for gaming, but struggles to keep up with the competition in productivity apps. Still, for 99% of the people, the 7800X3D performs way more than they’ll actually need.
Speaking of excessive needs, to cool the 7800X3D, I chose the ARCTIC Liquid Freezer III A-RGB. It is consistently being awarded as the best AIO and is usually the first choice for those who want to cool something way hotter than a 7800X3D, like a 14900KS or 7950X. It’s really affordable and fits well with the rest of the build so it was a no-brainer for me.
Do keep in mind that ARCTIC has released many versions of the Liquid Freezer III with little difference between them. The 360 mm A-RGB version offers the most features while being priced decently. 360 mm radiators are also much easier to install due to more support than 420 mm radiators with little performance difference.
Cooling the 7800X3D is a fairly easy task, but choosing the right motherboard isn’t. I needed something that is priced competitively and will take care of any future CPU upgrades down the line. That’s why for the motherboard, I went with the ASRock X670E Steel Legend – my personal favorite motherboard for the AM5 platform.
It’s incredibly loaded with features especially for its asking price. The VRM config is a super-strong 16-phase design and supports 4 DDR5 DIMMs up to 7600+ MT/s. On the back, there’s a plethora of USB ports, Wi-Fi 6E with Bluetooth 5.2, and gen 5 SSD and GPU support. If that wasn’t enough, ASRock decided to include a GPU anti-sag bracket as well.
There are a lot of great DDR5 kits to choose from but I stick to my simple rule – you simply can’t go wrong with any RAM kit that’s clocked at 6000 MT/s with a CAS Latency of 30 ns. For this PC I went with the TEAMGROUP T-Force Delta RGB 32 GB kit. I mainly chose this kit because it’s the only RGB kit that’s available in white and TEAMGROUP isn’t ripping off anyone by charging an arm and a leg for that.
Just like the RAM, choosing the SSD is the easiest part of any high-end build. Just go with a 2 TB Samsung 980 Pro and you’re good to go. It’s one of the fastest gen 4 NVMe SSDs, has a large 2 GB DRAM cache, and is very reliable.
Unlike the RAM and SSD, it wasn’t as easy to pick the right case; not because there are bad options, but because there are too many good options. Honestly, you could go with any case, but I decided to go big on the Lian Li Lancool III.
There are particularly 2 great things about the Lancool III that made me choose it over the other cases. Firstly, the airflow is incredible and the case has a lot of ventilation to let fresh air into the case; even the PSU shroud is meshed which lets even more air through the sides as there are no holes on the tempered glass side panel.
Secondly, building in this case is really easy – all the panels open without the need of any screws and the case is large so getting around anywhere is not a problem whatsoever. Cable management is really good thanks to the added cable management compartments in the rear panel which can do the cable management for you.
All in all, the Lancool III is a worry-free case and an easy recommendation.
Lastly, to power this entire PC, I went with the exceptionally powerful and feature-rich Corsair RM850e. It checks all the boxes for a high-quality PSU: it’s an 80+ Gold rated ATX 3.0 PSU with an included 12 VHPWR connector. It leaves plenty of headroom even after powering the 7800X3D and the RX 7800 XT which means that it’s going to last a very long time.
In conclusion, if you want an uncompromised experience with the RX 7800 XT, then with a budget of $1900 for this gaming PC you are covered. Every component was chosen carefully to offer great bang-for-your-buck while being the best in its category.
