My gosh, are you serious? How much does it help you overclock your 4870 over stock volts overclocking? How much are you able to overvolt it?

I'm so tempted to buy it right now just because of this... (at least, if it can reach 850-900 MHz without hardware v-modding) Is there another thread on this RT voltage adjustment tweak?
