Our Verdict on Each
The i7-5930K was a sensible mid-tier HEDT pick in 2014, offering nearly the same multi-GPU and multi-threaded capabilities as the higher-priced model while costing less. Today, it remains viable for specific workloads that need many PCIe lanes and memory bandwidth, but efficiency and single-thread speeds lag far behind modern chips.
Best for: A very low-cost used HEDT build that needs 40 PCIe lanes and quad-channel DDR4, especially for multi-GPU or many NVMe drives.
Read the full reviewThe i7-7800X offers quad-channel memory and decent multi-core performance for its era, but higher power draw and limited PCIe lanes make it a niche choice today versus modern mainstream platforms.
Best for: Budget upgrade on existing X299 platform with DDR4 investment
