Vibox IV Gaming PC (Ryzen 7 5700X, RTX 4060, Black) Review UK 2026

I’ve been building PCs for fifteen years, and I’ve learned something the hard way: you can swap out GPUs, add more RAM, upgrade storage on a whim. But the CPU? That’s the anchor. Change that and you’re likely looking at a new motherboard, possibly new RAM, and hours of reinstalling everything. So when Vibox sent over their IV Gaming PC with a Ryzen 7 5700X and RTX 4060, I wanted to see if this prebuilt gets the foundation right.

The 5700X is an interesting choice in 2026. It’s not the newest Zen architecture, but it sits in that sweet spot where mature silicon meets sensible pricing. After three weeks of gaming, rendering, and stress testing, I’ve got a proper understanding of what this system delivers. And whether it’s worth your money.

The Vibox IV lands squarely in that mid-range bracket. The Ryzen 7 5700X is essentially a 5800X with slightly lower clocks and better power efficiency. You’re getting 8 cores and 16 threads of Zen 3 goodness, which still holds up brilliantly for gaming in 2026. Pair that with the RTX 4060’s DLSS 3 frame generation and you’ve got a system that punches above its weight.

Competitors at this price include the AWD-IT Ranger (5600X with RTX 4060), PC Specialist Tornado R3 (similar spec but often with slower RAM), and self-built options if you’re confident. The 5700X gives this Vibox an edge in multi-threaded scenarios without sacrificing gaming performance.

In practice, the 5700X hits 4.5-4.6GHz on lightly threaded tasks and settles at 4.2-4.3GHz when all cores are hammered. AMD’s Precision Boost 2 does a proper job here, no manual tweaking needed. I saw zero thermal throttling even during extended Cinebench runs with the stock cooler Vibox includes.

The 5700X is basically AMD’s answer to “what if we took the 5800X and made it slightly less power-hungry?” You lose 100-200MHz on sustained all-core loads, but gain better thermals and lower power bills. For a prebuilt, that’s a smart trade. Vibox doesn’t need to spec an expensive AIO, and you’re not heating your room like a space heater in July.

I need to be honest about platform longevity. AM4 launched in 2016 and AMD supported it brilliantly through 2022. But we’re now in 2026, and AM5 is where new development happens. If you’re the type who upgrades CPUs every two years, this might frustrate you. The 5700X is realistically your ceiling unless you fancy spending £300+ on a 5800X3D.

However. Most people don’t upgrade CPUs that often. I’ve seen gaming rigs running Ryzen 5 3600 chips still delivering solid performance in 2026. The 5700X is faster than that, with more cores and better IPC. You’re looking at four to five years of relevance here, especially at 1080p and 1440p where the GPU matters more than the CPU.

Thermals are genuinely impressive. The stock cooler Vibox includes isn’t anything fancy – looks like a rebranded Deepcool Gammaxx 400 or similar – but it keeps the 5700X well below AMD’s 95°C limit. During three-hour gaming sessions, I never saw the CPU break 65°C. Even synthetic torture tests only pushed it to 78°C, and crucially, clocks stayed at 4.2-4.3GHz throughout.

The case airflow helps here. Vibox uses a mesh-front design with three 120mm intake fans. Positive pressure keeps dust out and temperatures reasonable. I did notice the GPU (which exhausts into the case) can warm things up during summer, but nothing concerning.

Honestly? The included cooler is fine for 95% of users. If you’re rendering videos for hours daily, consider upgrading to a 240mm AIO for quieter operation and lower temps. But for gaming and normal use, save your money.

I tested ten current titles at 1080p and 1440p, high settings, with the RTX 4060 doing the heavy lifting. The 5700X’s job is to feed frames to the GPU without becoming a bottleneck. Spoiler: it succeeds.

The 5700X delivers an 8% advantage over the 6-core 5600X in CPU-limited scenarios, and roughly matches Intel’s 12400F. Those extra cores help in modern games that actually use them – Cyberpunk 2077, Baldur’s Gate 3, and Starfield all benefit from having 8 cores available.

A few observations. First, the RTX 4060 is the limiting factor in most games at 1440p, which is exactly what you want. You’re not leaving CPU performance on the table. Second, competitive shooters like CS2 and COD absolutely fly. The 5700X’s low latency and high boost clocks keep 1% lows smooth, which matters more than average FPS when you’re trying to land shots.

Third, DLSS 3 frame generation is a leap forward for this system. In Cyberpunk with DLSS Quality and frame gen enabled, I saw 1440p performance jump from 64fps to 102fps. That’s the difference between playable and properly smooth.

Those Cinebench scores put the 5700X roughly on par with Intel’s i7-11700K and ahead of the 12400F by about 35% in multi-thread. For context, the 5800X scores around 15,000 points, so you’re giving up maybe 5% performance for better thermals and efficiency.

In real-world use, I exported a 10-minute 4K video in DaVinci Resolve (H.265, high quality preset) in 8 minutes 23 seconds. The 5600X takes closer to 10 minutes. Not earth-shattering, but those extra cores add up when you’re doing this regularly.

Streaming performance is where this system really makes sense. I ran OBS with medium x264 encoding (1080p60 output) while playing Warzone, and CPU usage sat at 78%. The stream was butter-smooth, no dropped frames, and in-game performance only dropped by about 8fps. Try that on a 6-core chip and you’ll see stuttering.

If you’re using NVENC encoding instead (which you should with an RTX 4060), the CPU barely breaks a sweat. I saw 35% usage while streaming, leaving plenty of headroom for Discord, browser tabs, and whatever else you’ve got running.

One thing to note: 16GB is tight for some modern games. Hogwarts Legacy and The Last of Us Part I can push past 12GB usage at high settings. If you’re keeping Chrome open while gaming (why do we all do this?), you might see occasional stuttering as Windows starts paging to disk. I’d budget for a 32GB upgrade within the first year if you’re a heavy multi-tasker.

The Vibox sits in the middle of the pack on price but edges ahead on CPU choice. The AWD-IT system saves you £50-100 but you’re stuck with a 6-core chip. PC Specialist often specs slower RAM which costs you frames. Building yourself gets you better components for similar money, but you’re doing the assembly and troubleshooting.

For someone who values their time and wants a warranty that covers the whole system, the Vibox makes sense. You’re paying maybe £50-80 over self-built cost for the convenience. That’s reasonable.
