Intel Core i7-7740X

Intel's "Kaby Lake" i7 chip on the Core X platform delivers good quad-core performance in line with the Core i7-7700K, but lacks extra PCI Express lanes or other standout features. Most users should stick with Intel's mainstream platform, or opt for a Core X chip that's a little more expensive.
