This is a ridiculous plan. Here is the high-end Mac of 15 years ago. If my father tried to push it on me now, I wouldn't want it. It's basically useless. Same will be true of your Mac Pro, whether it has 4 cores or 8, in 15 years. In fact, it will probably be pretty useless in less than ten years.
Comparing a Quadra to an 8-core Mac Pro fifteen years from now isn't comparable. The top-of-the-line three years after fifteen years ago (or ummm... 12 years ago) would be the 9500. 9600 if you pushed a bit further- not that it matters. Anyway, people still use those. They're heavily upgraded, true, but that's the point... you can upgrade the Mac Pro. You can't upgrade (heavily) anything else. 32 GB RAM will be enough in 10 years. I don't know about 15... but in 10, I can pretty much guarantee you it will. Oh, you won't be running high-end apps like Aperture is in today's turns, I'm not going to pretend you will. But it'll run.
We bought a Performa 6205CD when I was... I guess nine. It was great. Three years later it was a piece of garbage, and I couldn't wait to get rid of it. We then got a Beige G3/300. 64MB RAM, 2MB video card.. 6GB HDD.. super fast! I still use it at home when I'm back from college. Granted, it's also upgraded (maxed at 768MB RAM, three HDDs totaling 260 GB, a Radeon 32MB PCI video card, USB and an ATA/66 PCI card), but again, that's the point. It's only running a 500 MHz G4, but if I really wanted to, I could upgrade to a 1 GHz G4 (or hey, lol, a 1 GHz G3 and OC the bus to 83 MHz!

)
It's a great machine and it still runs. I do have my trusty 1.6 GHz Pentium M PC laptop next to it though (thinking of getting a new one).... since browsing can be kinda slow.
Anyway, a Mac Pro is more futureproof than this Beige, which was way more futureproof than that Quadra.
Umm, in 15 years it will be ancient, lol. Much like someone using a mac classic now.
-blinks- A Mac Classic is 28 years old. It was basically a cheaper rerelease of the original Macintosh, which is 32 years old. Max 4MB RAM ;x 8-bit Motorola 68000 CPU :x We have one in the basement. Kinda neat actually, you can boot from ROM by holding cmd+optn+x+o. Yeahhhh the screen was buggy ever since three years after getting it.
I know I'm not the first person to give an old computer away to a family member.
Definitely not.. plenty of people give away Beiges to their kids now.
15 years ago, we had CD-ROMs. Now days, you NEED a DVD-ROM to install software and most importantly, the OS.
Nah. I have Tiger on my machine and didn't use DVDs. I used CDs. Of course, those are burned. But hey, that's how it goes. Mediums are pretty much obsolete as it is now... all you need is a cable modem. We've had one since 2000... most people have them now. When you download at over 15Mbps, CD-ROMs and DVDs seem quaint.
Plus, your kid will hate you if all their friends have powerful pocket-sized computers and he still has a tower with a huge ass monitor.
Hehehehehe you have a point there. Though we'll always need large screens. Our brains and eyes don't change with the times
The Powerbook that I bought a little more than 2 years ago needs all available CPU and RAM to play movies in iTunes. In a couple of years, iTunes will become so much more complex that I won't be able to use it on the damn thing. Another example: my iPod has more storage space than the computer I had in 1997 had.
Yeah, but H.264 is an exception... it uses a ton of processing power, even by modern standards.. check how much it uses on a Core 2 Duo. It's significant, particularly given normal avi takes up less than 10-15%. iTunes isn't that much more complex.. just supports a few more things. It's kind of a clunky interface anyway, actually. I can run H.264 very smoothly at 640x480 just fine in DivX player on my PC, but it runs like crap at 320x240 via iTunes. That's a software issue, not a hardware one.
The software made 10 years from now won't even run on this computer. Your kids will love that.
Hm? I'm running Tiger 10.4.9 on a ten year old Mac.. works great. iTunes 7.6... iPhoto 5... Photoshop CS2... pretty much everything I want. What's the problem? =]
Lol, that was fun.
Anyway, I'm not sure there'd be much market for one. I don't imagine there'd be one at all from Mac users... as they'd just order what they want... and from PC users... well, they don't tend to ebay new things they can get for cheaper- particularly new parts. Maybe you should stick with the Uni-2.8? It's not worth risking murder if you can't pawn off the other CPU. Unless you know for sure you're capable of calming your wife down and getting her to put down that knife, that is =]
