Obsidian Vortex - NZXT H510, 5800x3d, RTX 3080 FE
by Frances L Posted on: 4/28/2025
Build Description
After months of researching and hunting for parts, I finally finished building Obsidian Vortex — a clean, efficient, and powerful gaming rig tailored for high FPS at 1440p without breaking the bank.
I built this PC using a mix of high-quality used components and carefully selected parts to get the best performance-per-dollar while keeping it visually sleek and thermally efficient. My goal was to play modern AAA titles with high frame rates, low temps, and zero compromise on stability.
I deliberately chose used parts where it made sense (like the GPU and CPU) to stretch my budget without sacrificing performance. Every part was tested thoroughly before installing.
The 5800x3D is still one of the best gaming CPUs thanks to its massive 3D V-Cache and efficiency.
RTX 3080 FE was picked this up used, and it's been rock-solid. Undervolted for better thermals and power draw, no overclocking. Delivers ~120–160 FPS in Black Ops 6 and 60–80 FPS in Cyberpunk 2077 at 1440p Ultra settings with temps around 65–72°C. The slight GPU undervolt helped reduce noise and power draw without affecting FPS, and so far, thermals are under control even under load.

Favorite Feature
One of the things I really like about this build is the undervolted RTX 3080 Founders Edition, it’s a standout piece both in performance and aesthetics.Despite being a few generations old now, this GPU still handles everything I throw at it with ease. The NVIDIA3080 FE design is sleek, compact, and looks premium without being over-the-top. It fits perfectly with the minimalist, clean aesthetic of the NZXT H510 Elite. What really makes it shine though is the undervolt I applied. It dropped the temps by several degrees and reduced power consumption significantly, all while keeping frame rates virtually identical. That means quieter operation, better longevity, and improved thermal headroom in a relatively compact case.
It feels good to breathe new life into used hardware and make it run better than stock, kind of like tuning a classic car to outperform something new right off the lot.
