I've been waiting a few months for a Mac Pro update and it finally happened. But, I need help deciding a few things. I do a lot of video editing and motion graphics, nothing too intense but nothing small and simple. I only dabble with Cinema 4D, not a heavy user. FCP, Compressor, Ae, Ps, and Ai are my main apps. I know I will at least get 6 GB for memory to start, and I already have 2 2TB hard drives to install. 1. Would the 6-core upgrade be worth the money, or would it be better spent on more memory? 2. Is the ATI Radeon HD 5870 worth the upgrade, or would it be better spent on more memory? I tried to compare the 5870 and 5770, but couldn't find much online in layman's terms. I'm sure Macworld and others will be doing comparisons of the cores. I will def. be waiting for some of that, but wanted to get some other input. I'm planning on getting this before the free iPod touch offer ends, so I can either sell it or use it for something. Obviously, I'd love to just upgrade everything as much as possible. However, I'm trying to only spend on what's worth it.
