Well it's not like any of you chipped in. But I am very grateful for all the helpful threads and insight those have offered to others which I have been reading from the shadows for months now. I got the Quad 2.66 all stock except 6 GB of ram. I am a graphic designer and photographer running CS3 and Lightroom 2 with Leopard. It is indeed quite zippy compared to my old Mac Mini. My Photoshop Benchmark test with 1 History state was about 18 secs. I imagine in another 6 months - a year when I upgrade to CS5, LR3 and SL I should see a significant speed increase which will be nice when processing huge raw files. Thanks again everyone!
