When building the best gaming PC for under $3000, you are essentially getting the very best flagship products and bringing them all together. A PC at this price point can handle pretty much anything you have to throw at it, including 4K gaming, virtual reality, fast video rendering, and plenty more. With a $3000 budget, you have the luxury of being able to tailor this build to your exact specifications. We’ve opted for a system that has maximum performance power, and beautiful aesthetics rolled into one. Before we take a look at what’s in this build, let’s go over exactly what we expect from this goliath gaming PC.

What You Get For Your $3000

The first thing most of us consider when looking to build a new gaming PC is the budget. It pretty much dictates what performance your new build will be capable of and how aesthetically pleasing it will be. Having said that, with a budget of $3000, those compromises and sacrifices become much less frequent. Want a powerful GPU? No problem. What about the best CPU on the market? That’s absolutely fine as well. With a $3k budget, you have the freedom to create a build that suits your requirements to the absolute tee.


After you’ve established what budget you have to play with, the next most important aspect to consider is the performance. Let’s be honest, this is a gaming PC, and you want the absolute best performance for your money. You’ll be glad to know that at $3,000, performance is not something you need to worry about. From a gaming point of view, the $3k build is going to be able to handle anything you throw at it. Yes, that means gaming at 4k in ultra settings with ray tracing on.

At the heart of this build lies one of Intel’s powerful i9 CPUs. Paired alongside that is the best consumer-grade graphics card ever made, this combination has enough power to run every AAA game title at 4k in ultra settings. Furthermore, streaming, multitasking, and hugely taxing workloads will become a seamless, enjoyable task on this rig. With this build, you won’t have to worry about game specs for quite some time; it’s the definition of an ultimate gaming PC.

How We Choose

Our team has years of experience behind them, building PCs for a range of needs and budgets. All this knowledge, combined with hours of research, user feedback, and onsite benchmarking, is what goes into choosing the best components for our builds. We look for value for money, how the components perform together and focus on gamers’ needs to make sure our builds are the best your budget can buy.

We build all these PCs ourselves, in-house, so trust us when we say we want to make them as good as possible. We actually use all these builds ourselves day-to-day in the WePC offices.

How We Test

We build each of our selected PC’s from scratch to make sure all the parts we recommend work well together, fit into the selected case, and provide the best performance possible for the price range. Once built, the PCs are used in the office for everyday work as well as a range of games from light to heavy-duty. While we test, we also run benchmarking tests to see how well our builds perform, all while keeping an eye on the temperature of the components themselves.

We tested our AMD builds against their Intel counterparts and found that these CPUs performed better across the board, and for a lower price. This is why we only recommend an AMD version.

At this price range, no compromises need to be made to accommodate the budget. The best gaming PC under $3000 literally does it all. It comes equipped with one of the best GPUs money can buy – paired alongside a stunning CPU that is the best in its class.

The Intel i9-13900K is, without a doubt, one of the best all-round CPUs on the market right now. The powerful chip is part of Intel’s13th generation, which is renowned for excellent performance across teh board.

It boasts an impressive 24-core/32-thread design, which makes it more than capable of handling the most intensive workload scenarios. Its single-core performance is still extremely high and is generally considered the best CPU currently available for the price.

MSI is no stranger when it comes to providing high-quality motherboards. Its MAG Z790 Tomahawk Wifi model is a fine example of premium. It might be one of the best Z790 motherboards for gamers, however, overclocking enthusiasts will want something a bit more substantial.

This board features excellent VRMs, a bunch of M.2 slots for future upgrades, and plenty of PCI-e lanes, including PCI-e 5.0, DDR5, and wifi6E.

We have selected the Corsair H150i Elite Capellix to take care of your 13900K. This AIO liquid cooler features three 120mm fans, which are, of course, quiet and RGB-cladded. The radiator is 360mm, giving you plenty of room for heat dissipation and keeping those fierce temps down, and installation is very straightforward.

When you look up the perfect RAM pairing this flagship CPU, fast speeds are easy to come by, however, we favor the Corsair Vengeance RGB kit for its reliability.

With 32GB at your disposal, you’ll be able to run every game you could imagine, plus stream, multi-task, and do plenty of heavy workloads too.

The $3000 build was designed with gaming performance in mind, for that reason, the first component that was chosen for this build was the immensely powerful RTX 4090. It comes to the table boasting an impressive 24GB of VRAM and an impressive cooling solution.

If you’re after one of the best consumer-grade graphics cards money can buy, look no further, this will play any game, in any setting, at any resolution.

Having a rapid SSD for your operating system and primary games is essential in the modern age of PC gaming.

SSDs, on average, offer massively increased performance over their HDD counterparts. The same difference can be said for M.2 SSDs over SATA ones. This TEAMGROUP MP33 M.2 is one of the highest performing SSDs on the market and has a 2TB storage capacity, which is more than enough for your O/s, most of your games, and some backup media storage as well.

A safe and efficient PSU is essential for a build of this quality, and that’s why we’ve gone for the popular Corsair RMx 1200W Shift gold-rated PSU. It offers superb efficiency and enough power to allow maximum overclocking potential from this PC. while more power than you need, it gives you ample headroom for quieter operation and future upgrades.

It is gold-rated, which means it’s extremely safe and efficient, exactly what a PC of this quality deserves.

Things To Consider


As we mentioned earlier, budget is a huge factor in any hardware purchase. It’s even more important when you’re in the process of putting eight components together in a custom PC build. Your budget can dictate your PC’s performance, aesthetics, future expansion, and features. Thankfully, our $3k build doesn’t have to compromise in common areas as we can pretty afford the best components out there. You’re in the premium-tier price spectrum now, and you’re able to tailor this build to your exact needs.

Upgradability & Future-Proofing

One of the most critical areas to consider after budget is the future-proofing and upgradability of your build. At lower budgets, such as $500-$800, you need to take this into consideration as your custom build will quickly become outdated. However, at $3,000, you don’t need to worry as much.

The CPU a modern AMD processor, which is widely considered as the best processor money can buy. The same can be said for the GPU and motherboard, as well. The motherboard has a tonne support, along with PCI-e 4 compatibility as well. The GPU is hugely powerful and comes with real-time ray tracing technology for the next generation of games. This means you won’t be needing to upgrade any of your major parts for the foreseeable future.


In modern computing, overclocking is one of the most sought-after features in any custom PC build. It’s an easy way to increase your computer’s performance at no additional cost. Win-win right? Sort of.

When you have the punching power of the CPU and GPU in this build, you don’t really need to overclock. That being said, thanks to the hugely impressive motherboard, this build is well ready for any level of overclocking you wish to throw at it, thanks to a powerful VRM design.

Ease Of Building

Thanks to the PC case in this build, the process of putting this build together just became a whole lot easier. It has a ton of room for cable management and plenty of room to maneuver parts as well. It’s worth mentioning that, poor cable management can actually affect your build’s airflow, which in turn, can reduce how efficient the hardware runs. The motherboard is also designed for an easy building experience. It has endless features, connectivity, and headers, meaning you’ll never be left short when expanding this build.

As a general rule of thumb, we would recommend using some form of anti-static device when building this PC, especially if you’re new to building. It might be necessary, but it certainly reassures your mind and you can concentrate on more important build aspects.

Non-Gaming Performance

Primarily, this is a custom build that was designed for maximum gaming performance, having said that, thanks to its monster CPU, 32GB of system memory, and large SSD, this build has a lot of potential outside of gaming.

It can handle almost any workload task you can throw at it, thanks to the powerful multi-threaded design. Pair that with the SSD’s rapid load times and 32GB of fast RAM, and you have a hell of a workstation as well.


You always want your PC looking good, even more so when you’re spending three grand on one. We understand the importance of aesthetics and considered that when building this PC.

The case is one of the finest to date. What better way to showcase your new $3,000 build than through tempered glass and the vibrant glow of multiple RGB zones? The case fans and components offer RGB, which further increases the overall look of this build.
