Note: The specifications listed above are subject to change. They were correct at the time the data was collected. Sometimes the SI changes the specs on the product page or updates it with another product/system. Kindly double-check the system specs. Another thing, the photos that these SIs/retailers used may not be accurate. The actual product that you will receive may look different from the photos.

Since most of these SIs do not mention the specific brand and model of the components they used on their prebuilt systems, I have to check whether the CPU is paired with a good motherboard. Most SIs try to save a few bucks by using a cheap B-series motherboard instead of an AMD X670 or Intel Z790/Z690. The Core i9 14900K(F) is an overclockable CPU, and they are only limiting the performance of the CPU by pairing it with a cheap motherboard.

While we can’t tell what specific components an SI will use on their prebuilt, at the very least, we should check the general specs of the system.

Yeyian Odachi Series RTX 4090 Prebuilt Gaming PCs – Best RTX 4090 Prebuilt with the Fastest (Gaming) CPUs

The AMD Ryzen 9 7950X3D is undoubtedly the fastest gaming CPU currently available. To date, Yeyian launched its Odachi gaming desktop series powered with the latest Ryzen 9 7950X3D processor. For those uninitiated, AMD’s Ryzen 9 7950X3D is a special CPU featuring a 3D V-cache technology. It’s a 16-core, 32-thread CPU with a maximum boost clock speed of up to 5.7GHz and a huge L3 cache of 128MB, which is dedicated to gaming. You can learn more about these new 7000X3D CPUs here, or check out a comparison between the 7950X3D and Core i9 13900K here.

Moving on, the Odachi series is not only available with a 7950X3D CPU, but it is also available with Intel’s 14th gen Core i9-14900KF CPU. A 360mm all-in-one liquid CPU cooler is used to cool the CPU, and the prebuilt has a decent 32GB DDR5 memory and a total of 4TB of storage capacity.

Based on the photos and marketing materials, Yeyian seems to use better parts and components than other SIs. The only thing that doesn’t impress me is the somewhat so-so-looking chassis they used with their prebuilt gaming PCs. Nevertheless, the main components seem to be decent. Check out more details, including their specs and pricing, below.

Skytech Azure Desktop Gaming PC – Also Good Intel-Powered RTX 4090 Prebuilt

Skytech has been in the SI business for quite some time. One of their latest gaming PC is the Azure, powered by an Intel Core i9-13900K and an RTX 4090 graphics card. It also comes with 64GB of DDR5 memory, which is more than enough for gaming alone but useful for productivity workloads. However, it only comes with a 2TB Gen 4 SSD, and you will need to buy additional storage for your game library and other files.

Skytech uses a 360mm AIO liquid CPU cooler to cool the Core i9 13900K, which is excellent. They also use a PCIE 5.0 1000W Gold PSU, which is great since it comes with a native 16-pin 12VHPWR cable. Although, it wasn’t mentioned in their marketing materials which specific brand or model is the PSU. Skytech offers 1 year warranty on parts and labor and lifetime free technical support. All units are assembled in the USA.

Thermaltake LCGS Frostbite i4790 Gaming Desktop – Thermaltake-Built RTX 4090 Prebuilt PC

Thermaltake is known for its cooling solution and chassis. But these past few years, they also ventured into selling their own prebuilt gaming PCs. The LCGS Frosbite i4790 is powered by an Intel Core i9-13900KF CPU and an RTX 4090 GPU. As expected from a water-cooling company, the Frostbite i4790 features a 360mm AIO liquid CPU cooler. You can expect that some of the components in this prebuilt are from Thermaltake.

Aside from the CPU cooler and the chassis, Thermaltake is also using their Toughram XG RGB D5 memory and perhaps a Thermaltake PCIe 5.0-ready PSU. Although the latter is not confirmed, Thermaltake does sell PSUs. Although this prebuilt will work great out of the box, you may want to upgrade its storage and memory in the future. 2TB is not enough for a gaming PC, and you can extract more fps by using a faster DDR5 memory, especially with an Intel system.

FAQ Regarding Prebuilt Gaming PCs

Pros of prebuilt gaming PCs

One of the most obvious advantages of a prebuilt gaming PC is that it’s already assembled and is expected to work out of the box. You only need to take it out of the box, plug in the monitor, keyboard, mouse, and power, and you are good to go. Some system integrators may have additional instructions or reminders, so check out any reading materials they provide.

Another advantage is when you encounter a problem, or something isn’t working properly, you only need to contact the SI’s customer support. Unlike building the system yourself, you’ll have to determine which component(s) is/are causing the issue. And you’ll have to contact the manufacturer of that particular component. The same can be said with warranty claims. If you need to claim a warranty, just contact the SI and not the individual or specific manufacturer.

Most system integrators mentioned above are reputable and have been in the business for quite some time. However, note that even if they are a veteran in the industry, these SIs are not infallible. Sometimes they do commit mistakes, and sometimes there can be shipping issues.

Some System Integrators include freebies, usually a mouse and a keyboard. So that’s a bit of a plus, I guess. These gaming PCs also have the Windows operating system. They are, after all, expected to work out of the box. So, you only need to download and install the games and other apps you need.

Cons of prebuilt gaming PCs

Prebuilt gaming PCs are usually more expensive than building the system yourself. Also, these companies don’t charge the same rate. Some SI charges are higher compared to others. That is why most people say you should build it yourself to save some cash. However, this option is not for all, especially if you do not have the time or knowledge to build one.

Another disadvantage of buying a prebuilt gaming PC from an SI is that you don’t know what specific brand/model of components they will use on the prebuilt. I’m sure they won’t use high-end or premium components. At least the CPU is constant since it is produced by two companies only, either Intel or AMD. But most of the SIs do not disclose what brand and specific model of motherboard, graphics card, SSD/HDD, or power supply they use; and so on. While some do disclose what components they use, most are still unclear.

Should I get an Intel-powered gaming PC or an AMD-powered gaming PC?

Choosing between an AMD system or an Intel system is a personal preference. Below are some pros and cons of each system:

Pros of the AMD Prebuilt:
The Ryzen 9 7950X3D is one of the fastest gaming CPU, aside from the 7800X3D. Meanwhile, the Ryzen 9 7950X (non-X3D) is (slightly) better in productivity workload. AMD’s AMD5 is not a dead-end platform. It means the current X670 motherboard will support the next-gen CPUs from AMD. Not to mention, it’s more efficient than Intel’s current generation of Raptor Lake (Refresh) CPUs.

Cons of the AMD Prebuilt:
Currently, the Ryzen 9 7950X3D is slower than the Core i9 14900K in games like CS: Go and Rainbow Six. I don’t know if AMD will have a fix for this or not. Also, the idle power consumption tends to be higher than Intel’s system.

Pros of the Intel Prebuilt:
Intel’s CPU is faster in some games. However, since the difference is small, it’s almost negligible. The Core i9-14900K/F has Performance Cores and Efficient Cores. Thanks to its E-cores, the idle to light load power consumption is lower than AMD’s.

Cons of the Intel Prebuilt:
Unfortunately, the Z690/Z790 is a dead-end platform. Intel’s next-generation CPUs will not be compatible with the current motherboards. And by “next-generation”, I am talking about the “15th gen CPUs” and not the recently released 14th gen Raptor Lake Refresh. The 14th gen CPUs are generally compatible with the current Z690 and Z790 motherboards.

It is reported that Intel will use a larger socket for their Meteor Lake CPUs. So, there is no upgrade path if you opt for an Intel system. In addition, the Core i9 13900K and 14900K’s power consumption can go as high as 200W++, depending on the scenario or workload.

Any Good 4K Gaming Monitor?

If you plan to get an RTX 4090 prebuilt, do not use it or pair it with a 1080p monitor. It will only limit the performance of the GPU, even with a fast CPU. At the very least, get a 1440p, ultrawide 1440p, or better yet, a 4K gaming monitor.

These prebuilt gaming PCs do not come with a monitor. So, if you don’t have a monitor yet, I listed some of the best high refresh rate 4K gaming monitors here.
