Flashed my 470 with a custom BIOS.

@HammerOn: At 1.087V, under full load during Furmark, my GPu doesn't go above 83 deg. I still have headroom temp wise. If increasing voltages allows me to OC further, to the point where I am limited by temps, I'm willing to go liquid cooling.

EDIT

Sigh...so at 770/1700 its stable at 1.075V. If I increase clocks to 800/1700, I lost display within 5min of Furmark even if I increase voltage to 1.15V or more.
Why is it that I can't push my Core clock anymore even if I supply more voltage. There's no problem with temps.
