I'm about ready to upgrade to a G5 tower, but I'm having some trouble deciding on which one I should go with. I have TiBook right now, and am finding it a little sluggish when it comes to audio editing. I'm a protools and soon-to-be logic user, and am considering either the single 1.8ghz G5, or the Dual CPU. I don't do anything insane in terms of audio stuff, 7 or 8 tracks at most, but what worries me about the single CPU model is that the frontside bus is so much slower than the dual. Will this be a significant decrease in performance? Now that I think about it. will protools/etc even make use of the processing power of two cpu's? Basically I can get the single with lots of ram/better graphics, or the dual with less ram and a few less bells and whistles. Any recommendations based on my situation would be greatly appreciated.
