Hello,
I am looking for help with a two PC set up, can anyone review my plan, offer any opinions and maybe answer my questions?

PC1
Sequencer and Recording:
Sonar + a slave hard drive for recording
Hardware:
Echo Gina audio with SPDIF in and midi

PC2
Samples and Synths - Things like:
Kontakt2
Reactor
EWQL Gold
GPO
Hardware:
ECHO MIA audio with SPDIF out
Midiman USB interface

The way I plan to connect them is:
Midi keyboard controller to PC1
PC1 to PC2 via midi cable
PC2 back to PC1 via SPDIF (MIA to GINA)

1) Are the applications separated correctly for best utilization of 2 CPU's? I understand the advantage of keeping something like Reactor on it's own CPU, but does it make "CPU sense" to keep things like GPO and EWQL on a separate PC from Sonar?

2) If so How would I run them - VST/DXi/Standalone? - What setup would allow me to run the most simultaneous instrument tracks in Sonar?

3) Which PC should get the fastest CPU? - (I have a P4 3.2 and a P4 2.8)

Thank you very much for your consideration and opinions - Your time is appreciated
