With that amount of ram and the need to do video editing given the I would use windows XP given the choices here and configure 5gigs of ram as a ram disk to crunch the data for the video editing as this would reduce overheads and demands on the disk io and increase performance as well.
What's the point of running a any Windows 64 OS when your running a majority of 32bit applications on it.. the performance is minimal and simply because the OS can address additional memory it does not mean the applications can. Personally speaking I would like my applications to make the most out of my system and do not care about the OS as this is nothing but a platform used to run my applications
I ultimately would use Linux myself
