Background: iPhoto with 53,000 photos or vid clips iTunes with 1,456 TV Shows, 662 Movies, 33,478 songs iMovie with about 1TB of family movies 6 AppleTV's (2nd gen) at each TV in the house I've been running on this platform that now gives me regular "beach-balls"... I think it's getting a bit long in the tooth. - 2006 Mac Pro - 2x 3Ghz Dual Core Intel Xeon - 6GB 667 MHz DDR2 RAM - 4 2TB internal drives - 4 2TB external drives for backup (using SuperDuper!) 1. Should I just beef up the RAM on my current machine? iPhoto uses about 1GB to simply run with that large a pic database. iTunes uses about 800MB to run its extensive library. 2. What should I get? 3. Should I get a new Mac Pro? (If I get a new MacPro now, it doesn't have Thunderbolt.) 4. What about an iMac with a stack of external drives? Thanks in advance for your help... I've been racking my brain on this decision.
