Feature Image - 4000D 3080 Build


As prices for top-end GPUs slowly get closer to MSRP, picking up one of Nvidia‘s most powerful cards is becoming more viable. Today we’ve built a gaming PC that utilises some of the best parts money can buy, including one of Intel’s latest 12th gen CPUs, the i5 12600K, and MSI‘s Suprim X rendition of Nvidia’s RTX 3080.

We’ll be breaking down each of the individual components in our Main Components section, and further down you’ll find some peripheral choices, and benchmarks of this system giving you some real-life context, followed by a gallery of this awesome build!

Main Components

Intel Core i5 and Core i7 - 3080 4000D Build

CPU: Intel Core i5 12600K or Intel Core i7 12700K

Starting off the build is a little bit different to our typical articles. We’ve provided two CPU options from Intel’s 12th gen range, the Core i5 12600K, and Core i7 12700K. If you plan on building your PC entirely for gaming, then the i5 12600K will be a suitable option which is perfect for most games. The i7 12700K will be more for those that want to build a workstation system and gaming PC. With the higher cores, threads and clock speed the 12700K is more fit to handle intensive workloads like rendering and video editing.
