What reviewers say

Reviewers find strong rendering and workstation performance, with a useful improvement over the earlier 32-core PRO model. It often offers a better balance than the 64-core 5995WX for creative applications, but the expensive processor, motherboard and memory make it a specialist choice rather than a mainstream upgrade.
