What I would consider doing is the idea of making your G5 your Logic machine (or whatever DAW you use) and then have the MacPro be your VE3 machine since it will be the one that needs all the horsepower.
By all means test this theory, but I personally disagree in the idea of using the G5 as the main Logic machine & the MacPro as the sample slave. Playing sample libraries like VSL does require some CPU, but the actual bottleneck for streaming samples is not CPU, rather RAM & Disk speed. The VI player is VERY efficient, and so is VE. In fact, I am ALMOST able to stream an entire orchestra from my Dual 2.5GHZ G5 alone! However, 2 instances of Amplitube (guitar amp FX plugin) brings my G5's CPU to its knees. If you plan on running MIR or any other high processor reverbs, you will only be able to do this on a MacPro. The G5 processor just cant handle it (MIR) and/or the algorithms are not being coded for PPC (see the new vienna reverb in VS, which unfortunately is intel only!) BTW, I use a dual 2.0 Intel mac mini as a VE slave, and VE is running at 25% CPU, yet my poor FW400 external disk & 2GB RAM are maxing out, further confirming that my bottleneck is not CPU, rather disk speed/RAM. <br><br>
Thus I personally recommend using the G5 as a sample slave (max out RAM & add additional disks via SATA card), route the separated audio signals into Logic via aux tracks, and use the Mac Pro as your CPU machine for reverb/FX. At least this is my plan.
