Hellow all, I currently run a 2009 8-Core 2.26GHz Nehalem Mac Pro with 8GB RAM. I work mostly with audio, some video and occasional gaming. Now, for a secondary setup, I need to pick up another machine. I need this new one to last another 5 years. I've been having some trouble deciding between the iMac and Mac Pro. So far, with respect to audio, the 2009 Mac Pro has been more than sufficient. I run huge amount of plugins and track count, also some CPU intensive soft-synths. I feel true multi-thread support is still not present in audio (esp Logic has this stupid 1 core overloading issue). Not everyone has gone 64-bit either, so I haven't seen the need for the highest end fully maxed out Mac Pro, unless I want to make it last for a longer duration. I only looked at the iMac, since the geek-bench scores were quite impressive and compares very well with my old machine. Thunderbolt is another advantage. I can wait until Jan for a mac pro update, but that's about it. I either need to pick up a maxed out iMac '11 or a 8-core Westmere Mac Pro by then. I use only 1 PCIe device, which can be stuffed into the old machine. And I'm hoping thunderbolt opens up a whole range of possibilities next year. All this is considering the fact that the Mac Pro update doesn't show up in time for me and I have to choose between the iMac and Mac Pro. iMac maxed out is definitely cheaper, don't need to buy a display, 3.4GHz etc. PCIe is not relevant to me, I'm hoping the multiple drives I need can be sorted using Thunderbolt. What advantage would the current Mac Pro (medium range) have over the iMac'11 including it's Thunderbolt potential in terms of expandability and performance? Thank you.
