What reviewers say

Reviewers valued the extensive PCIe connectivity and quad-channel memory, but found performance close to cheaper Ryzen 7 processors in many workloads. The expensive motherboard and cooling requirements weakened its value for ordinary PCs. It mainly suited buyers who needed the platform's extra expansion rather than a gaming-focused build.
