What reviewers say

Reviews find strong per-core and multithreaded performance, but only a modest improvement over the 3770K and little reason for recent Sandy Bridge or Ivy Bridge owners to upgrade. Integrated graphics improve for light games and media work, though demanding games still need a separate graphics card. Overclocking requires suitable cooling and a new LGA1150 motherboard.
