OK, So I was all set to get a used Mac Pro tower for audio production off ebay thinking it will easily outperform any laptop. I currently have an early 2008 MBP Core 2 Duo (3288) and on Mac Benchmarks a 2.8GHz early 2008 8-core gets almost triple the score (9105). No brainer right? Well I've just checked Benchmark scores and the latest 17" MBP has a higher score than the old 8 core - 10045. Is i7 really that powerful? A 4-Core is faster than an 8-core Xeon?? Price wise a new MBP straight from Regent Street is not much more than a used Mac Pro, especially when I consider I would have to buy an additional cinema display for use with the tower, the price then is nearly the same. Having a brand new laptop obviously wins, the only thing that could limit me there is the number of connections. My current MBP has all ports constantly connected plus there's a powered USB hub with three more devices connected on one of them. The other issue is HDD space and speed. I'd be going for 2TB at least with a tower, and would be limited to 750GB and 5400rpm with the laptop.... Hmmm... opinions peeps?
