3dmark03 is currently running at 600mhz core 1800mhz mem. i am seeing tiny artifacts in the nature test so it looks like aftermarket cooling is definately going to be needed for 1.4volts on a 7900gt. the test passed at 580mhz and i scored 19997 in 3dmark03. pissed off that i didnt get to 20k i cranked the clock speed to 600 and we shall see what it scores....
Nice

So did the bios actually improve your maximum overclock?

Here are 2 new biosses with a 20mhz delta clock so you can really determine if you can overclock higher than before. The first is a 1.3v bios and the second is a 1.4v bios. With the stock cooler 1.3v might be a better choice.

I'd like you to test the difference in temperature at the same coreclock with the 1.2v stock bios, the 1.3v bios and the 1.4v bios.

1.3v bios 20mhz delta:

1.4v bios 20mhz delta:

Good luck with it
If it really works then it might also be possible to get 1.5v at a 7800GTX 256mb
