I'm pretty happy with my new MacPro 2.26 dual (see sig below). I run a couple of instances of Altiverb or IR-L, 20-25 audio tracks, tons of EQ and Compression, a couple of Amplitubes, Addictive Drums, Stylus RMX with effects, a few VIs, and it still doesn't go over 40% most of the time.

I haven't maxed it out yet on any session so far. I usually run at 128 buffers, but have gotten a few glitches using EA extensively when doing that, so sometimes I'll raise it to 256, which is still very usable for me. (Vocals are monitored externally, so I don't have to deal with microphone/headphone latency issues).

16 cores show up in PTLE 8.01 and I have 15 selected for RTAS. I don't think it's crashed yet with Protools, although it crashed with Sibelius once.
