Can someone recommend a pci 7.1 or 5.1 surround sound card for an G5 intel mac pro? I'm using Logitech speakers.... There are several for PC but hardly any for Mac. Thanks

One method is to go external - a firewire interface.

EG, the M-AUDIO - ProFire 610 - High-Definition 6-in/10-out FireWire Audio Interface with Octane Preamp Technology (http://www.m-audio.com/products/en_us/ProFire610.html) has two mic preamps, and 10 line-level analog outputs. I have the earlier FW410, it works fine for this application. Plus, when you eventually get a computer that doesn't have PCI, it still works.

Street price about $365...

M-audio has a good record of maintaining mac and pc drivers for their products (very important!), and, this one can also serve as a hardware host for ProTools M-Powered versions.

Thanks Seth, I'll be looking into that
