I'm fairly new to both the Mac Pro and video editing. I'm using Production Premium 5.5 which will soon be upgraded for free to CS6. I've been running it on a 2008 MP 3.1 with 20gb ram and a 4870. I've noticed that photoshop, after effects and premiere don't even use 4 cores but they do use a lot of ram. The only programs that I've seen use 6+ cores is encore and capture one (my RAW converter). I'm probably going to sell my MP 3.1 and use my MP 1.1. Here's what I'll have in the 1.1. Dual 2.66 12gb ram with 2 open slots HD 2600 256mb or the 4870 1gb 500gb 7200rpm for main drive 160gb raptor for scratch drive 160gb raptor for current work drive 2tb 5400 drive for storage of older projects Possible upgrades that I can see. I'll have $400 - $500 for upgrades. add 8gb ram - $200 upgrade cpu to dual quads - $200 but having watched the usage on the 8 core MP I don't see this as having a lot of bang for the buck 256gb SSD for main drive - $200 Once the programs are loaded into memory I don't see this as adding much to the overall performance. I'm more concerned about speeding up the processing of files than I am about opening programs. Increasing the ram is probably much more useful. upgrade the video card - seems for less than $500 Macvidcards can provide a cuda card that's suppose to speed up Adobe apps significantly. I just don't know which ones and by how much. I'm not sure what the priority for the upgrades should be. I know that by going back to the 1.1 MP I might be stuck on Lion going forward. That's fine. This computer will be for editing, not for "normal" use. I'm thinking this order: video card ram processors maybe SSD's down the road If I go video card then that's all I can do for now. If I go ram and processors then I can do both of them now. Will the video card result in greater gains then the processor/ram combo? If the video card then which one? I'd like to have 2 monitor ports (dvi or display port) plus an HDMI port.
