I have experience with the desktop / home studio version of Pro Tools which comes with the MBox external sound card / mixer, and it works quite admirably on an Intel iMac (2.16Ghz Core Duo, 2 Gigs of RAM.) I've also seen studio Pro Tools run w/o hiccup on boxes as old as Power Mac G4 Quicksilvers, so I'm not sure if, and/or why there is a need for a true dual processor / SMP motherboard. People are still buying old G4 PowerMacs for Pro Tools work on Craigslist and eBay for a few hundred $$$.
I actually have never used Pro Tools on a PC (since the Mac is so entrenched in audio content creation work,) but if ProTools works fine on old Macs, then my guess is you wont need a powerful PC for most versions. Actually, since you're constantly writing and reading from the hard disk, it may be better to invest in a fast Raptor SATA drive, or for even better performance, Serial Attached SCSI (although you'd need a serious add-on card or a server motherboard for the later.)
Mark.
I use PTLE 7.1. It seems to run better on macs than PCs.. I know this cause I have a macbook that I use it on for mobile tracking.. PCs running pro tools seem to require more beefing up in order to run a good amount of plugins. My old dell can run PT fine but once I put any reverb plugs on anything the CPU is completely drained. My goal is to have ample power to be able to run more plugins simultaneously than I'd ever need, so a really beefed up PC for mixing would be ideal since I cant afford a mac pro.
