Does your 24/7 work load benefit fron HT on? If not, turning it off buys you a budget of less vcore/more CPU clock that you can spend in any proportion you like. Also,
what CPU loads are your RAW file convertions and video editing producing, and what temp levels?

What I especially like about your post is that your D0 earns you more than just bragging rights, you get real world benefits from the extra power of the D0...great results!
