I wish I would have come across this thread a few days ago Nightmare, like you I also just got my 2nd GTX680 (after getting the first one at launch) and my original card is flashed with the BIOS file you needed! (both cards are the same model from eVGA - P4-2680 2GB Reference but have different BIOS files). Although I'm knowledgeable when it comes to this stuff I'm not an expert, like Nightmare should I flash one of my cards so that their both running the same BIOS file (I never actually tested my new 2nd card, I just installed it and reinstalled the driver for SLI)? I assumed that they would both have the same specs (GPU/MEM/Voltage specs) given they are the same model from the same vendor with the same advertised specs? Please let me know guys if there is any benefit to both cards having the same BIOS file (keeping in mind that they already have the same clocks and voltages). Last but not least, I'm assuming they both have the same clocks and voltages despite having different BIOS versions since both cards are the same but I will set Afterburner to log GPU/MEM clocks and voltages and get back to you all with the results - maybe my assumption is incorrect!
