interesting ... i'll have a look, gigabyte are currently looking into it , the only reason i thought it does require a driver is the fact that the cpu and ram scored much lower in the windows experience index when i went from 32bit windows 7 to 64bit ... ( cpu went from 7.4 down to 6.5 and ram from 6.8 down to 5.9, also graphics scores were a fraction lower )
And yes it's the full RTM release ( 32bit & 64bit )
Edit: just got this reply from support .....
