The GeForce GTX 680 Mac Edition was a high-end graphics card by NVIDIA, launched in April 2013. Built on the 28 nm process, and based on the GK104 graphics processor, in its GK104-400-A2 variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 110, which can be problematic with newer DirectX 12 titles.

Added on 08/04/13: Dr. Stealth has an excellent thread on how to flash the GTX 680 4GB models at this link, and what 4GB models were successfully flashed. Currently both Newegg and Amazon are out of stock for the EVGA Mac Edition GTX 680. 2015 proton gen 2 owners manualgen 2 owner s manual. I am somewhat new to flashing VBIOS roms but I managed to flash the GTX 680 Mac Edition ROM on a my EVGA card last night. EVGA part number is 02G-P4-2684-KR. The GTX 680 I have is a Mac edition, so the boot menu and boot display do appear while starting up. If anyone has a GTX 680 dual display configuration working, I’d like to hear some details. The GTX 680 is on Apple’s list, and System Information does show it to be a Metal-compatible card, which makes the dual display glitch more frustrating.

it really looks like that nvflash isnt able to successfully write to the eeprom.
the thing i want to try out is program this little bitch with an external programmer.
but i dont understand how since the bios dump is only 179kb and the eeprom has 256kb of space.
another way i was thinking about was to edit the device id.
but i dont know how.
the 660ti is '10DE 1183'
the 680 is '10DE 1180'
so.. does anybody in here got an idea or can tell me how to write the 179kb bios file to the eeprom ?
