    Hi guys. I can't get my EVGA GTX 780 to work, it shows only black screen, and i guess its doing a reboot cycle.. I also tried powering the card with my 450W FSP x5 BOOSTER, same prob. I've tried 10.8.5, that was scary cause either USB 3.0 or Nvidia Web Driver did work. What to dooo? :confused: :apple: :confused:
