Hi! I purchased a mac pro 8-core (2 x 2.8 Quad-Core Xeon) in August 2008. I've been happy with it but am intrigued by the idea of the newest Mac Pros. I currently have 10GB RAM, 5x500GB HDs, wireless, and the NVIDIA 8800 GT in there. Should I consider selling my current Mac Pro (if so, how much?) in favor of buying one of the new 2x2.26 Nehalem-based machines? I'm a user of PHotoshop, Logic/Audacity, business apps, and VMWare Fusion. I'm intrigued by the ability of the new processors to run emulation (Fusion) faster. I'd be happy to move the HDs from the old machine to the new if it made sense. Any ideas on how much the swap might cost? Any arguments in favor of or against making this switch? I admit that part of it is novelty of something new -- but I also wonder if the newer Mac Pros will be much better poised for the future (3-5 years) and will take much better advantage of SL. Thank you for your thoughts!
