I installed bios level 0063 on the Intel DZ77RE-75K via the F7 method and so far no big issues except fast boot. After boot fast is enabled, I noticed some video display issues (1920x1080) with the Windows sign on screen, Windows desktop background and with one of my games. Turning off fast boot eliminates the issue.
Shutdown times with Windows 7 and Windows 8 is 6-7 seconds in Legacy mode. I haven't booted in UEFI mode.
