Currently, my main computer is a "Hackintosh". I built the rig with the following specs a little more than 2 years ago:
Mac OS X 10.10 Yosemite
i7-4770k @ 4.3Ghz
Corsair H100i
Gigabyte Z87X-OC
32GB Corsair Vengeance LP 1866Mhz
2x SLI EVGA GTX 770 Superclocked with ACX Cooling
Cooler Master HAF X 942 Blue
Corsair HX750 PSU 80+ Gold
Samsung 840 Pro SSD - 128GB
3TB Western Digital Black 7200rpm HDD
1TB Western Digital Black 7200rpm HDD
I love the flexibility of having decent hardware AND the better OS.
Finder is diabolical software.
