I´ve recently updated my persolal gaming rig to be able to play newer titles on higher settings, it is a bit of a budget build since i´m a student. But it´s more than enough for me. I bought a big power supply to be able to run multiple cards in the future without the need for a new one, it did only add about £30 on the original price. The prices aren´t the ones i payed since i live in Sweden, but the parts and the performance is the same. The two DVD drives was sent to me even though i only paid for one (they didn´t want the other one back).
I´ve yet to push the CPU to its limits, i ran with the motherboards recommendation at 4.25GHz.
I´m running Windows 8.1 Pro off the Corsair Force LS, and OS 10.9 off the Corsair Force 3. And everything works great since Nvidias web driver update for OpenCL (GK110B).
I´ll answer any questions hackintosh or component related in the comments. Any feedback is appreciated :)
