I saw this system spec and decided it would be my first hackintosh. I built it system with an i7-3770k but with an Nvidia GTX 650 (one of the recommended cards on the buy page). I followed BitterMelon's instructions exactly, including to not install the video card until after I got it working with the onboard video. Everything seems to work and boot up okay with onboard, but when I plug the 650 in and reboot with my monitor attached to the 650's upper DVI port, it shows the apple logo then switches to a gray screen. At that point nothing happens, and I have to do a hard shutdown. The onboard video auto disables and there's no signal there. I did try to do the unibeast with the 650 installed, but I couldn't get video to the display.
There appear to be several threads with multiple possible solutions to getting cards working, but I thought I'd ask here since someone may have used a similar card on this mb and figured this out before I go down the wrong road.
Suggestions?
