Best NVIDIA RTX 3080 Gaming PC Desktops

Best RTX 3080 Gaming PCWith the release of NVIDIA’s new RTX 3080 GPU, we’ve put together a list of the best prebuilt dekstops with an RTX 3080 in them.

We recently put up a guide on the best RTX 3090 gaming PCs and, so, naturally, we have decided to follow it up with a list of the best RTX 3080 gaming computers.

Just like with the RTX 3090, it is currently very difficult to find an RTX 3080 available for purchase on its own. So, many gamers who are ready to upgrade to NVIDIA’s newest high-end GPUs have been left in frustration with the dessimated stock.

One way that you can get around having to wait for the RTX 3080 to become available is to just buy a prebuilt gaming desktop that already has an RTX 3080 in it. I know that’s not the best solution for gamers who prefer to build their own system, but if you need a new gaming PC and you can’t wait for the newest RTX graphics cards to come back in stock, buying a prebuilt system is currently your best option.

And, in this post, we’ve highlighted a handful of the best RTX 3080 prebuilt gaming computers currently available.

As of right now, CUK (Computer Upgrade King) has the majority of RTX 3080 (and RTX 3090) prebuilt computers on Amazon. And, of their variety of systems, our pick for the best RTX 3080 gaming desktop right now is their Mantis PC.

The CUK Mantis comes with an Intel Core i9-12900KF processor, 64GB of DDR4 memory, a 1TB solid state drive, a secondary 2TB hard drive, and an 850-watt gold-rated power supply.

The Mantis also comes with a tempered glass PC case with a full-length PSU shroud, an AIO cooler, and six green LED-lit fans.

Overall, the Mantis is powerful enough to run any game you throw on it at max settings on even higher resolution displays. So, if you don’t want to build your own gaming PC, or you just can’t wait to get a new RTX 3080 GPU, the Mantis is one of the better prebuilt options currently available.

2. CUK Continuum Micro

Top small form-factor RTX 3080 desktop

CUK Continuum Micro Gamer PC RTX 3080
  • Intel Core i9-12900KF
  • NVIDIA RTX 3080
  • 64GB of DDR4 RAM
  • 1TB SSD / 3TB HDD

Our Rating: 9.3/10

For a smaller version of the CUK Mantis, the Continuum Micro is worth checking out. It’s basically the same system as the Mantis listed above, but it comes in a smaller micro-ATX case.

The Intel Core i9-12900KF, the RTX 3080 GPU, and the 64GB of RAM are going to be more than enough to max out any game you through at it. However, you don’t really get a discount over the Mantis due to the smaller form-factor. Both systems will cost about the same.

So, really, this will all come down to aesthetics and whether or not you want a system that comes with a smaller or larger footprint.

If you are looking for something a bit more affordable than the Mantis edition PC listed above, check out the Skytech Chronos listed below.

3. CUK Mantis Ryzen

Best workstation RTX 3080 PC

CUK Mantis Gaming Workstation PC RTX 3080
  • AMD Ryzen 9 5950X
  • NVIDIA RTX 3080
  • 128GB of DDR4 RAM
  • 1TB SSD / 4TB HDD

For those of you that need a system that can double as a powerful gaming PC and a high-end workstation, the Mantis Ryzen edition is probably your best bet. You will pay a premium to get this Mantis edition desktop, but it will come with an AMD Ryzen 9 5950X processor, 128GB of RAM, a 1TB SSD, a secondary 4TB hard drive, and an 850-watt power supply.

The Ryzen 9 5950X will provide similar in-game performance to Intel’s i9-11900KF and 11900F, but where it will offer more performance is in multi-threaded and CPU-intensive applications.

So, for gamers who also need a PC for graphics design, game development, serious spreadsheet work, video processing, etc. the Ryzen 9 5950X is the better option. And, with 128GB of RAM and a total of 5TB of storage, you’ll have plenty of memory and storage space for all of your needs.

Ultimately, at just a little under ~$4,000, you will pay significantly more for the better multi-threaded performance, the extra memory, and the additional storage space. But, if you need the extra computing power, then the Mantis Ryzen 9 5950X edition is likely the best option for you.

4. Skytech Chronos

Most affordable RTX 3080 prebuilt desktop

Skytech Chronos Gaming PC Desktop RTX 3080
  • AMD Ryzen 9 3900X
  • NVIDIA RTX 3080
  • 16GB of DDR4 RAM
  • 1TB Solid State Drive

For about ~$500 less than the CUK Continuum Micro, you can get the Skytech Chronos RTX 3080 desktop. In the grand scheme of things, the Skytech Chronos will offer similar in-game performance to the Continuum Micro despite having a slightly different hardware configuration.

Where the Continuum Micro opts for an Intel Core i9-12900KF and 32GB of RAM, the Skytech Chronos goes with the Ryzen 9 3900X and 16GB of RAM. And, while it’s always nice to have additional memory, for the vast majority of games, 32GB of RAM isn’t going to offer any noticeable advantage over having just 16GB of RAM.

And, also, just as with the Ryzen 9 5950X above, the Ryzen 9 3900X is going to offer solid performance in multi-threaded applications, while providing more than enough in-game performance to meet even the most extreme gamers’ needs.

So, the reality is that, while this Skytech gaming desktop does come in with less RAM, the specs are still good enough to where the system will not be limited in the kind of in-game performance you can achieve. It does also only come with a single 1TB SSD, but if you’re just looking for the most affordable RTX 3080 gaming desktop right now, you could always add more storage (and more memory) later down the road.

5. $2,500 Gaming PC Build

A solid RTX 3080 DIY PC build

Thermaltake Core X71
  • Intel Core i7-12700K
  • NVIDIA RTX 3080
  • 16GB of DDR4 RAM
  • 1TB Solid State Drive

Normally, I suggest building your own gaming PC rather than buying a prebuilt gaming computer. However, if you’re looking to build a new high-end gaming PC right now, you’ll be hard-pressed to find an RTX 3000 series graphics card available (on its own) for a price that makes building your own PC a more affordable option than buying a prebuilt system.

So, really, if you want a new NVIDIA-based system, the cheapest option at this time is to go with a prebuilt desktop that already has one in it or get a custom-built system.

But, if you can get your hands on an RTX 3080 GPU, this build right now would be a good option to pair it with. And, while you can customize anything in this build, this option above provides a good enough mix of hardware to allow the system to perform extremely well in any task you throw at it, whether it be gaming at 4K, or doing CPU-intensive work.

This build would normally come in significantly cheaper than the options listed above. If we assume the MSRP pricetag of ~$700 for the RTX 3080, you could build this system for just under ~$2,000. However, as graphics card prices are currently inflated, it is tough to find an RTX 3080 currently available for under $1,400.

So, as of right now, building an RTX 3080 gaming PC probably isn’t the most cost effective option.

What is the Best RTX 3080 Gaming PC?

Right now, the best RTX 3080 gaming PC is the CUK Mantis. If you’re looking for the most affordable RTX 3080 desktop, though, then the Skytech Chronos is worth checking out.

Ultimately, the NVIDIA RTX 3080 GPU offers extreme graphics processing performance and will be powerful enough to allow you to max out games on just about any settings and resolution configuration. And, while there aren’t many RTX 3080 graphics cards available for purchase at the moment, there are a handful of companies that have RTX 3080 prebuilt desktops available for sale. So, whether you’re looking for the cheapest possible RTX 3080 desktop or a workstation-grade gaming PC with an RTX 3080 in it, there should be an option in the list above that will suit your needs.
