I'm consistently hitting the wall with my Dual 2.0ghz, 4GB of RAM G5 system while trying to mix typical pop/rock projects (that is, I keep getting the system overload message, even when I freeze most of my tracks). I'm getting ready to trade up to a recent-model MacPro, but I'm a little confused as to which one to get. Yes, I know I should always buy the fastest CPU I can afford, but I can't afford that one, and I'm wondering whether one of last year's models will work for me. Specifically, I'd love to get away with picking up a 2008 quad-core or even a dual-core machine, and I'm hoping that people who are mixing comparable projects on those computers can chime in with their experiences. My goal is to be able to mix, at the highest i/o buffer setting, without having to freeze tracks, or worry about triggering the dreaded system overload message. Here's the rundown on one of my typical projects: Tracks: - 28 tracks of audio - 10 virtual instruments (mostly Rhodes, GPO piano, Wurly, EXS24 percussion, rather than CPU-intensive synths) - BFD2 for all drums FX: - UAD1 eqs and compressors on many tracks - NI Guitar Rig 3 on 2 to 4 guitar audio tracks - 2 or 3 PSP Vintage Warmer 2 plugins - I don't use many other 3rd party plugins, or Logic's more CPU-intensive plugins - I do like to set up a few longer delays as send FX (semi dub-style), which really seems to put a hit on my processor As I said, I'd love to hear from people who are doing similar projects on 2008 MacPros, but anyone's input would be very welcome. Thanks!
