Our Verdict on Each

A solid 2014 CPU that still handles basic tasks, but struggles with modern workloads and lacks Windows 11 support.

Best for: The Core i7-4790 is a processor that should only be encountered in legacy systems. If you already own a motherboard with this chip, it can still serve adequately for basic web browsing, office applications, and older games. However, it is not recommended for purchase today. The LGA 1150 platform is dead, meaning there is no upgrade path. Additionally, the lack of official Windows 11 support and high 84W TDP make it inefficient compared to modern budget processors. Avoid buying this CPU for new builds. It is best utilized by keeping existing hardware alive for light duties.

A legendary CPU that was the first to hit 4.0 GHz base. It still holds up for basic use but is outdated for modern gaming.

Best for: The Core i7-4790K is a legendary processor that should only be considered today if you are maintaining an existing LGA 1150 system. It still offers decent performance for basic computing and older games, and its unlocked multiplier allows for some overclocking fun. However, it is not recommended for new builds. The lack of Windows 11 support, high power consumption, and outdated instruction sets make it a poor choice for modern workloads. If you are building a budget PC, modern processors offer vastly superior performance and efficiency.
