Hello, after 5 years I will eventually replace my Macbook Pro 2,2 GHz. I'm considering following models: - iMac 27" 3,4 GHz i7 (with Belkin Thunderbolt Hub for external drives and peripherals) - 2.100 Euros + 200 -300 for the hub - Mac Pro 3,2 Quad Core Xeon - 2.600 Euros + a second monitor (150 Euros) - wait for the new iMac coming sometime between september 2012 and mid 2013 (I'm very impatient...) - ??? - I could have a used Mac Pro (almost 2 years old) for 2.000 Euros: Mac Pro 3,33GHz 6 Core Westmere EP ( Model 5.1 ) 12GB RAM 2 graphics cards: NVIDIA GeForce GT 120 and AMD Radeon 6870 1024MB 1x 2.0 TB HD e-Sata PCI-e controller card I'm working with Logic 9, a Focusrite Saffire 24 Pro DSP firewire interface. My projects tend to get quite big (60+ audio and virtual instrument tracks) with many buses and plugins and I want the new one to last another 4-5 years. My budget is around 2.000 - 2.500 Euros (the new Mac Pro is around 2.600 which is also okay) What would you recommend for best performance, expandability and longevity? Thanks!
