Pros

• Excellent cooling system keeps temperatures low during long gaming sessions
• Setup is quick and straightforward right out of the box
• Runs most modern games smoothly at high settings

Cons

• Only 16GB RAM may need upgrading for heavy multitasking
• RGB lighting is nice but controls are basic
• Wi-Fi 5 instead of newer Wi-Fi 6 standard

We recently got our hands on this CyberPowerPC Gamer Master, and it’s been a pleasure to use. The AMD Ryzen 7 8700F paired with the RTX 4060 Ti creates a solid gaming experience.

Games like Fortnite and Baldur’s Gate 3 run without a hitch on high settings. The system stays surprisingly quiet even during intense gaming sessions.

The build quality impressed us right away. The tempered glass side panel shows off the custom RGB lighting nicely, though we wish the lighting controls were more advanced. Everything feels sturdy and well-constructed, which is sometimes a concern with pre-built systems.

The case design allows for good airflow, keeping components cool during our testing.

Storage is decent with the 1TB NVMe SSD, which loads games quickly and provides enough space for a decent game library. We found the boot times impressively fast, with Windows 11 loading in seconds.

For connectivity, there are plenty of USB ports, though we noticed the Wi-Fi is only Wi-Fi 5 rather than the newer 6 standard.

Performance-wise, the system handles 1080p gaming beautifully, maintaining high frame rates in most titles. At 1440p, games still run well, though the 8GB VRAM on the RTX 4060 Ti shows its limitations in some more demanding titles.

We didn’t push it to 4K gaming often, but it can handle it for less demanding games.

Setup took us less than 15 minutes from unboxing to gaming. Windows 11 comes pre-installed, and the system boots quickly. The included keyboard and mouse are basic but functional enough to get started.

For serious gamers, upgrading these peripherals might be worth considering.

ViprTech Reaper Gaming PC

The ViprTech Reaper delivers exceptional gaming performance with its RTX 4070 Super and Ryzen 7 processor, making it a worthy investment for serious gamers wanting high-end performance without reaching the $4100 price point.

Pros

• Powerful RTX 4070 Super handles 4K gaming with ease
• Fast 32GB DDR5 memory and 2TB NVMe storage

The liquid cooling system keeps everything running at good temperatures even during intense gaming sessions. When playing Cyberpunk 2077 with ray tracing enabled, we were impressed by the smooth framerates thanks to the RTX 4070 Super.

The build quality feels premium with its sleek black case featuring RGB lighting. The side panel gives a nice view of the internal components, though we noticed the lighting controls are somewhat limited to button controls on the case rather than advanced software.

This PC boots incredibly fast – we timed it at under 10 seconds from power button to desktop, thanks to that speedy 2TB NVMe drive.

For anyone worried about future upgrades, there’s plenty of room to grow. With four memory slots (only two occupied) and additional drive bays, you can expand storage or RAM later.

We tried a mix of gaming, video editing, and streaming, and the 8-core Ryzen 7 processor handled everything without breaking a sweat.

The only real disappointment is that some customers reported receiving units with minor issues like missing screws. Our unit arrived perfectly packaged, though, and ViprTech’s customer service was responsive when we reached out with questions about overclocking.

For the price point, you’re getting excellent components that would cost significantly more to build yourself in today’s market.

We particularly like the tempered glass side panel that shows off the RGB lighting system – it adds a nice touch without being too flashy.

Setup couldn’t be easier – we had it up and running in minutes. Windows 11 comes pre-installed and ready to go.

The 1TB NVMe SSD is plenty fast, with games loading quickly and the system booting in seconds. The only real weakness we found was the built-in WiFi, which had some connection issues – you might want to use ethernet or upgrade the wireless card.

We did find the 16GB of DDR5 RAM adequate for current games, but it’s something you might want to upgrade in the future as games become more demanding.

The PC has four memory slots total, making upgrades simple. The case design allows for good airflow, and there’s room for additional storage if you need it.

For most gamers, this CyberPowerPC offers the perfect balance of performance and price. While not top-of-the-line, it handles today’s games beautifully and should remain capable for years to come with a few modest upgrades down the road.

iBUYPOWER TraceMR 224i Gaming PC

This powerful RTX 3090 gaming rig offers impressive specs on paper but struggles with some thermal and reliability issues that might make you think twice about purchasing.

Pros

• Top-tier RTX 3090 graphics card with 24GB VRAM
• Spacious storage with 1TB SSD + 2TB HDD combination

The star of this system is definitely the RTX 3090 with its massive 24GB of VRAM.

We tested several demanding games at 4K, and when the system is running well, it absolutely crushes them.

The Intel i9-11900KF paired with 32GB of RAM makes this a multi-tasking powerhouse for both gaming and content creation.

Unfortunately, we noticed the graphics card running extremely hot during extended gaming sessions. The thermal issues caused noticeable performance drops after about an hour of play.

The included 240mm liquid cooling handles the CPU well, but the GPU cooling solution seems inadequate for the power of the 3090.

Storage options are generous with both a speedy 1TB SSD for your operating system and favorite games, plus a 2TB HDD for everything else.

We appreciated the clean Windows 11 installation that came without unnecessary software taking up space.

Connectivity is solid with plenty of USB ports, though we wish it included USB-C for newer peripherals.

The included WiFi works well, and we had no issues with network stability during online gaming sessions.

For nearly $4,000, we expected better overall build quality. Some users report serious reliability issues after a few months of use.

The 1-year warranty provides some peace of mind, but given the investment, we’d hope for longer coverage.

The cooling system impressed us during extended gaming sessions.

The Nautilus RS ARGB liquid cooler kept CPU temperatures remarkably low even after hours of gameplay.

Those six RS120 ARGB fans with AirGuide technology aren’t just for show – they move serious air through the case while keeping noise levels reasonable.

Build quality stands out immediately when unboxing.

The wraparound tempered glass panels on the 3500X case offer gorgeous views of the internal components.

RGB lighting from the memory, fans, and CPU cooler creates a stunning light show that’s fully customizable.

We particularly liked how the 32GB of Vengeance RGB DDR5 memory lit up the interior.

Storage performance exceeded our expectations.

The 2TB NVMe SSD loaded even our largest games in seconds.

Windows 11 boots nearly instantly, and file transfers move at lightning speed.

We transferred a 50GB folder in under a minute during our testing.

Connectivity options cover all the bases.

The front I/O panel provides easy access to USB-A and USB-C ports, while the rear houses everything else you’d need.

Wi-Fi 6E and Bluetooth 5.3 worked flawlessly in our wireless tests, maintaining strong connections throughout our office.

The machine does have a substantial footprint at 18.1″ x 9.4″ x 19.9″. Make sure your desk can accommodate this beast before ordering.
