Hi peeps, I've got a late 2008 MBP 2.5 GHz Core 2 Duo, 4GB RAM, 320GB HDD. It's from the last 17" aluminium series before they introduced the unibody. I do audio production with external synths and DSP boxes and I still manage to max out this laptop and crash Logic Pro on regular basis. Not to mention the perpetual lack of hard drive space. In short I need to upgrade... I'm thinking of buying a second hand Mac Pro with 2 x Dual Core Xeons, either 2.66 or 3.0 GHz, bit more RAM and loads more HDD space. This would likely be the original Mac Pro series from 2006. How much faster would this configuration be than my current laptop considering it's 2 years older? I don't have infinite funds but I do need the fastest computer I can buy. Not bothered about losing portability, the laptop is firmly fastened to my desk and every port is connected to something and then some.
