Socket LGA1155 What reviewers say Reviews find strong CPU performance and improved integrated graphics and Quick Sync encoding, though demanding games still need a separate graphics card. They differ on the size of the CPU improvement; TechRadar finds modest gains over Sandy Bridge, while Expert Reviews sees larger gains with its stock-cooler setup. Overclocking remains capable but offers no clear generational advance in TechRadar's testing.
