We recently tested the Skytech King 95 and were blown away by how well it handles demanding games. The Ryzen 7 9800X3D is a perfect match for the RTX 3080, eliminating any CPU bottlenecks that might hold back your graphics card’s performance.
During our testing, we saw consistently high frame rates even in CPU-intensive titles.
The liquid cooling system is truly impressive in real-world use. Even after hours of gameplay, the processor stayed cool under pressure. This matters a lot when pairing with a high-performance GPU like the 3080, as overall system thermals stay manageable even during intense gaming sessions.
Boot times are practically instant thanks to the blazing-fast 4TB Gen4 SSD. We particularly appreciated how quickly large games loaded – even massive titles with long load screens on other systems popped up in seconds on this rig.
Connectivity is excellent with plenty of USB ports for all your peripherals. The case design allows for easy access if you ever want to upgrade components, though with this level of hardware, you likely won’t need to for quite some time.
For anyone looking to get the absolute most from their RTX 3080, this processor and overall system configuration eliminates performance bottlenecks. We found that games ran smoother and more consistently than on systems with less capable CPUs paired with the same graphics card.
NVIDIA RTX 3080 Founders Edition (Renewed)
The renewed NVIDIA RTX 3080 Founders Edition offers exceptional 4K gaming performance that makes it a smart choice for gamers wanting high-end graphics without paying full retail price.
Pros
- Nearly new condition with professional testing
- Powerful 1440p and 4K gaming performance
- Covered by Amazon Renewed Guarantee
Cons
- Some units may arrive with minor cosmetic issues
- Lacks original packaging in some cases
- Higher power consumption requires good cooling
We recently got our hands on this renewed RTX 3080 Founders Edition, and we’re honestly impressed with the condition. Our unit arrived looking almost brand new, with the iconic dual-fan design still looking sleek. The card feels solid and well-built, which is typical of NVIDIA’s Founders Edition models.
In our testing, this GPU crushed everything we threw at it. Modern games at 1440p run buttery smooth, usually well above 100 FPS with settings maxed out. Even at 4K, most titles maintain a steady 60+ FPS on high settings. The 10GB of GDDR6X memory handles texture-heavy games without breaking a sweat.
Heat management on our unit worked really well. During extended gaming sessions, the card stayed reasonably cool thanks to NVIDIA’s flow-through cooling design. We did notice the fans can get audible under heavy load, but they’re not annoyingly loud compared to other high-performance GPUs we’ve tested.
Best CPU Pairings for RTX 3080
- Intel Core i7-12700K or higher
- AMD Ryzen 7 5800X or better
- Intel Core i9-10900K for maximum performance
The renewal process seems thorough, as everything from the DisplayPort outputs to the power connectors worked flawlessly right out of the box. We appreciate that it comes with Amazon’s Renewed Guarantee, giving us peace of mind with our purchase.
For anyone building a high-end gaming PC or workstation, this renewed 3080 offers tremendous value. It delivers performance that rivals current-gen cards at a more affordable price point. Just make sure your power supply can handle it – we recommend at least a quality 750W unit.
AMD Ryzen 9 5900X
The Ryzen 9 5900X is hands-down the best CPU to pair with an RTX 3080 thanks to its incredible 12-core performance that handles both gaming and productivity tasks with ease.
Pros
- Amazing multi-tasking with 12 cores and 24 threads
- Excellent gaming performance with 100+ FPS in popular titles
- Great value compared to similar Intel offerings
Cons
- Runs hot under heavy loads
- Doesn’t include a cooler in the box
- Higher power draw during intensive tasks
We recently tested the AMD Ryzen 9 5900X with our RTX 3080 setup, and the combination is simply outstanding. This processor delivers exceptional performance across every task we threw at it. Games that previously stuttered now run buttery smooth, and the 4.8 GHz boost clock ensures you’re never waiting for your system to catch up.
The 12-core, 24-thread design makes this CPU a multitasking monster. We noticed zero slowdowns when gaming while streaming or running background applications. For content creators, the extra cores make video rendering and 3D modeling significantly faster than previous generation chips.
One thing to note is that you’ll need a good cooling solution. During our testing, the chip ran hot under full load, easily reaching the mid-80°C range with a basic air cooler. We recommend at least a quality 240mm AIO liquid cooler to keep temperatures in check.
Quick Tip: Make sure your motherboard has the latest BIOS update before installing this CPU to ensure compatibility and optimal performance.
The 70MB of cache memory helps tremendously with gaming performance. We saw significant frame rate improvements in CPU-bound games compared to older Ryzen processors. When paired with the RTX 3080, you’ll easily push past 100 FPS at 1440p in most modern titles with settings maxed out.
For productivity, this chip truly shines. We cut our video rendering times almost in half compared to the previous generation. The AM4 socket compatibility means you can likely upgrade your existing AMD system without changing your motherboard, provided it supports PCIe 4.0.
Power efficiency is another strong point. While gaming, the CPU draws reasonable power, though it can get hungry during all-core workloads. Still, it’s more efficient than comparable Intel options we’ve tested.

- Only 500GB storage may fill up quickly with modern games
- 450W power supply limits future upgrade potential
We recently got our hands on this MXZ gaming desktop, and it’s been a solid performer for our 1080p gaming sessions.
The RTX 4060 is the star of the show here, easily handling popular titles like Fortnite, Apex Legends, and GTA V with impressive framerates at high settings.
The case looks fantastic too, with those six RGB fans creating a light show that’ll brighten up any gaming space.
The Ryzen 5 3600 processor is getting a bit long in the tooth now, but it still holds up well for most gaming needs. We did notice some CPU bottlenecking in more demanding titles, but for everyday gaming and multitasking, it handles things smoothly.
The 16GB of DDR4 memory at 3200MHz gives you enough headroom for gaming plus browser tabs or Discord running in the background.
Setup couldn’t be easier with Windows 11 Pro already installed. We just plugged it in, connected our peripherals, and were gaming within minutes.
The 500GB NVME SSD loads games quickly, though we’d recommend adding extra storage eventually. Most modern games eat up 50-100GB each, so that space fills up fast.
The included Wi-Fi adapter was a nice touch, saving us from running ethernet cables across the room.
Perfect for: Gamers who want a hassle-free entry into PC gaming without building their own system.
For the price point, this system offers good value with its RTX 4060 GPU. The A320 motherboard is basic but functional, though it does limit future CPU upgrades.

Buying Guide
Choosing the right CPU to pair with your RTX 3080 isn’t always easy. We’ve put together some key factors to consider before making your purchase.
Budget Considerations
Your budget will greatly impact your CPU choice. High-end CPUs offer better performance but cost more. Mid-range options provide good value for most gamers.
Some CPUs might seem cheaper upfront but require expensive motherboards. Factor in the total cost including cooling solutions.
Performance Needs
Think about what you’ll use your PC for. Gaming needs differ from video editing or 3D rendering requirements.
Tip: If you’re mainly gaming, prioritize single-core performance. For content creation, more cores are better.
Compatibility Factors
Not all CPUs work with all motherboards. Check socket type and chipset compatibility before buying.
Important CPU Specs to Compare
| Spec | Importance | Impact with 3080 |
| Core Count | Higher is better for multitasking | 6+ cores recommended |
