"...I'm not as excited about 64-bit access as I once was, because I'm able to access all the affordable RAM I need to access right now."
I noted your coolness to 64-bit as early as last year's NAMM, I believe. I think the "Batzdorf Method" shows a healthy non-emphasis on the dream of one computer doing it all. Over the last year, I've stopped holding that torch. Yeah, it'll come one day -- but I've stopped actively waiting for it.
"...if I remember right I had a sequence playing when I did one of those tests." Again, that amount of RAM you've loaded is clear and inspiring. But I'd like to know what kind of CPU price you're payng just for the loaded RAM when the transport is running without anything playing back. I've seen your System Memory posts, but not CPU readings. But only at your convenience.
"I've been upgrading machines every couple of years since the mid-'80s, so this is quite a change." Agreed. About '04, we crested a VI threshold. The discussions I read now have more to do with ease of use.
"Is that normal?" I don't know if it's normal, but it's what I face all the time.
"...whereas I just use a "cheap" reverb sound for composing to save on cpu and get more sequencing done." In my search for more CPU, I was alarmed to realize how *little* Space Designer was asking of my computer. I had wrongly assumed that it was a major culprit. Finally in a diagnostic session, I removed them from my song, and the CPU savings was negligible. It led me to wonder if the caution against such things was a bit out-dated, like the way we use to worry about MIDI choke. But your results may vary.
"I would start with Apple's own refurbs." Yes, me too. I bought my Mac used from Sweetwater and still got some service and return protection. But the sad truth of the Mac universe is, there aren't a whole lot of deals out there. As Nick once pointed out, even after new lines debut, "old" Macs might drop about 150 to 200 dollars. Nice, but sometimes not worth the wait and unlike the jaw-dropping deals we can see in PC's.
