I don't want my graphics drivers resetting all the time because of this.
Anyone have a solution? How hard is it for someone to make a modified 680 driver with boost 2.0 capabilities? A friend once told me that there is something in the 700s hardware that allows for the new boost. This isn't the case apparently so there must be a software workaround?
Thanks to anyone who helps in advanced
I made a flash-ready zip with a BIOS for reference 680s.

It's a modded stock NVIDIA branded GTX770 BIOS with 1111Mhz base clocks, 1202Mhz Boost and 1.212v unlocked. Memory is at a conservative 3250Mhz so should run fine.
Also unlocked the full fanspeed range @ 30-100%.
Power limit is gone. Temp limit set to the stock 80c.
Flash with nvflash (is in the package) using commandline.
Nvflash -protectoff first just to be sure.
Then just do nvflash -4 -5 -6 biosname.rom and type YES (CAPS) when it asks for id mismatch overwrite.
Press y when it asks whether your sure you wanna flash.
Wait for it to finish flashing.
Reboot and reinstall drivers from cache (C://NVIDIA/DisplayDriver/3xx.xx/insertwindowsversionhere/setup.exe
Add a extra overclock to the 1202Mhz boost through any OC software like MSI Afterburner.
Memory also fully clockable by offset.
