So I recently received my EVGA GTX680 Mac Edition video card. I installed it in slot one and everything seemed to be working for about a day. The computer started randomly restarting and it wasn't too bad at first but then it got to the point where I couldn't even get to the login screen before it would reboot. I swapped the stock ATI 5770 back and it booted right back up. I RMA'd it back to Newegg so we shall see what happens when the new card gets here. Anyone have this happen?
