Hey guys. I have been using iMacs for the past 4 years and am going to make the jump to Mac Pros and I have a few questions.... Current setup: 24"iMac 2.4 C2D 6GB RAM SSD boot / app disc, Aperture 3 library on external through FW800 + Time Machine External and "Random" video/music external My goal: Make a machine the runs Aperture 3, Photoshop CS4 and FCP (occasionally) screamin fast. I am starting to feel bogged down working on 21 megapixel RAWs in Aperture 3 and 1080p footage in FCP I would love ANY feedback on my current plan: -Get a used basic Mac pro (Any advice on a good year / processor to look for?) from craigslist or another forum I buy/sell stuff -Get it up to 12GB RAM -Take the SSD from my iMac and put it in as boot / app drive (Will this work plug-n-go?) -large eSATA drive for aperture libraries. Would I see a worthwhile benefit from something like this using RAID 0 mode? -large internal drive for time machine. Will this backup a RAID 0 drive like it would any other? I clearly have a minimal understanding of RAID tech! -large internal drive for music/movies -gfx card... Can I upgrade this myself if I get an older machine? Any recommendations? Thanks guys EDIT: Found one of these on craigslist w/ 24" dell I was going to get anyways for $1500... Good deal?
