I named this system Regina, and I love it. I hadn't really expected noticeable improvements in speed from changing over from Princess, but in fact it's very noticeable. I had not realized just how computationally intensive some Internet tasks are. In general, everything runs faster, and smoother, and I've searched my log for glitches to tell you about, but I haven't found any. The computational load for each task may be small, but it adds up, particularly if everything demands attention at once.
Dual processors come into their own smoothing out peak loads.
I also have 256 megs of memory in Regina. That seems to be more than enough. The sound is Intel AC97 built onto the motherboard and is quite good, the equivalent of all but the top of the line Creative sound boards. I can hear and understand speech including Techweb broadcasts. If you're a sound purist you'll have your own ideas of what you need anyway.
