Intel Core 2 Quad Q6600 4-core LGA775
The 65nm Kentsfield architecture with its 8MB L2 cache and four physical cores made this one of the first accessible quad-core processors for the LGA 775 socket. Its strong overclocking headroom on the 1066 MHz FSB, often reaching 3.0GHz, gave it legendary longevity in budget builds. This processor is best for retro PC enthusiasts restoring a period-correct Windows XP or early Windows 7 gaming system.
