My GTX 780's asic is 64,5%
Do you think I will be able to get a higher OC in my GTX 780 without rise vcore with vBios or some EVGA BIOS?
P.D: Sorry for my English
What's "too much"? Having 1.2v to get 1149Mhz stable or just having the 1.2v?
For the record, 1.2v aren't "too high" at all. nVIDIA plays extremely safe when it comes to voltage limits. If nVIDIA allows 1.2v, then I am sure it is pretty much "risk safe".
As for the rest, is almost impossible to answer your question. The overclock abilities of any given card are more about the GPU than are about the vBIOS. If you get a very good GPU in the lottery, it will OC very well at low voltages no matter the vBIOS driving. I expect more improvements by simply updating drivers with a mild voltage bump than by simply changing BIOSes without voltage increments at all.
But one thing I know for experience: ASIC is a myth at best, and BS at worst. My reference 780 has a 64% ASIC and it boosts up to a stable 1276Mhz @ 1.200v.
