Hi All: I need opinions on this dilemma from you wise gentleman. I own an original 2.66 GHz dual-core Intel Xeon Mac Pro that I purchased back in 2006. It currently has 9GB RAM and 4 HDs in it totaling 3.25 TB of storage. I use this machine (affectionately named Juggernaut) for the following: Primarily for music creation with Logic Studio, Ableton Live 7 and various AU plugins Light iMovie editing, although I will likely begin to dabble with Final Cut Express now since I just purchased a brand new AVCHD camcorder for recording 1920x1080 HD video Usenet/Bittorent Handbrake/Visualhub/MKV transcoding for my PS3 Streaming of HD video to PS3 over AEBS 801.11N network Typical web surfing, mail, and maintenance of a 170GB+ iTunes Library Needless to say, this machine has served me well over the years, but I am keenly interested in the upcoming Gainestown Mac Pros, so much so that I am contemplating selling this unit on eBay before the new units drop and picking up a Unibody 17 MBP as my desktop replacement for the interim. I realize that the Mac Pro in general is probably overkill for what I use it for, but I gravitated to it because I like the security of knowing that I have infinite expandability and a relatively-future-proof machine with the ability to house multiple drives. With that being said my questions are a follows: 1. Am I nuts for considering selling this unit in preparation for a new Gainestown Mac Pro unit whenever that may be? 2. With my usage, would I see any significant gains with that new model especially considering that if I got the new model, it would be awhile before Id be able to upgrade the memory to any amount larger than 4GB? 3. If I decide to keep my current Mac Pro and install Snow Leopard on it, will I see a significant performance difference? Enough gains to justify keeping it? Ive searched all the boards and read up on the Nehalem/Gainestown stuff but Im still a bit fuzzy on it all which is why I decided to seek the sage advice of you all. So tell me am should I sell my old MP and wait for the new MP or keep what I have and run with Snow Leopard? Thanks in advance for all opinions.
