I have been thinking of adding a second GTX 680 to my system, I have a top of the line Creative labs sound card in PCIex 1_1.Will the card be ok there or should I move it to PCIex 1_2 which would be my only other option?

I am still running the shipping bios, the system is rock solid but this bios seems to have an older version of the cpu microcode 07 Does anyone know what version is in the new 0711 bios and is it worth upgrading? Thanks in advanceAsus Maximus VI Hero...
