Jeremy – thanks for your input. That is good to know about Sony support, that’s a huge deal for my department.
Here’s a bit about my scenario, to answer your question:
Within my department (web delivery for a news network), we are running Vegas on 11 machines (4 for editing, 7 for network rendering). We are testing HP z800s with the goal of upgrading our edit machines to them. Any type of software/OS upgrade must be presented to management with a detailed proposal, and such upgrades would involve our support staff.
So, it’s not necessarily that Win 7 64 isn’t an option for me, it’s that I need to compile as much data as possible before I propose making such a step, especially since we’d ideally want all 11 machines running the same OS/software. If this were my home office, I’d be much more open to trial and error. Since I often don’t have that option, I rely on the vast resource that is… you guys!
