Friend is looking to build a hackintosh. Are his specs compatible? If yes, which OSX should he aim for?

He’s running windows with specs below. If I understood him correctly he’s thinking to dualboot.

Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz Kingston 2x4gb DDR3 MAXIMUS VII RANGER Z97 Samsung SSD 840 EVO 250GB WDC WD10EZRX-00L4HB0 1TB NVIDIA GeForce GTX 770
