Hi, I've been reading this forum for a while in hopes that someday my IT department would realize that I actually need a Mac Pro. Well, surprise, surprise, they're now ready to pull the trigger. Like really soon. So, I'm stuck with picking from what's available now vs. waiting for Sandy Bridge/Thunderbolt potential goodness down the road. We'll be getting RAM and HDs from other sources so I'm not worried about that (as many Gb's as I can convince them to buy). What I do want to know from the smart people here is which processor I should lobby for. I edit HD video (P2 and 5DMKII footage) in CS5 (soon to be 5.5) and do a bunch of still photography as well (Lightroom/Photoshop). That's going to be the main use for this machine. So, should I go for the 12-core? Or will the 8-core hold up for me over the next couple of years? They want my spec sheet by the end of the day. Thanks in advance.
