You seems to fail to see that other people have different use case than yours.

I know a lot of audio engineers that buy Mac Pros 4,1 and 5,1 to run Mavericks or El Capitan because ProTools version they need only run with these Macs and with these old macOS versions. Everything else is secondary to ProTools and don't matter. Sometimes it's not even ProTools, but a plug-in or a very specialised card that only runs with Mavericks.

Not everyone needs the things that you need.
 
UK ebay
a dual CPU tray is £530 :confused:
cheapest dual CPU cmp for £600 and that's with no upgrades & HD 5770
so in the UK it's fairly good.

This always winds me up, I've seen dual trays listed for £500-£700, and then a few rows below a complete system (with lower spec CPUs) for £400-£600.

Even once you plow £200 into CPUs and some other upgrades it doesn't make much sense to buy the trays, even single trays with a 6 core Westmere seem to fetch £200-£300, and I've never even paid that for a complete single CPU 4,1/5,1.

I just picked up another dual 4,1 at the weekend locally for £240, even if I slide that tray out with the E5520s still in it and bung it on eBay I could probably make a profit and still have the rest of the machine to part out...spend £100 on some 5680s or 5690s and It'd sell for double again. Madness!
 
I disagree. I think the 4,1 and 5,1 Mac Pros have been so popular because they can run the latest software and, once Catalina is released, they'll become less popular (like the 1,1 - 3,1's did once they lost OS support).
The audio world is one in which support for current Digital Audio Workstation software is all that matters. While I concur with your remark that the 4,1 and 5,1 MPs will be less popular overall, for people with specific uses, Aiden's "run away" is a silly and inaccurate blanket statement.

Most, if not all, DAWs will run under Mojave for years to come. I'm still running Sierra with my DAW, which is up to date. I'll likely move to Mojave when I get a chance to experiment during some studio downtime.

Someday, the 7,1 will readily available used and compatible CPUs will be selling for cheap on eBay; perhaps we can then replicate the value proposition that has been the 4,1/5,1 experience.
 
As I mentioned in the post you responded to: I just purchased a PowerMac 7300 for a specific use case. Does that mean Aiden's "run away" statement is incorrect for that system?

Thank you (and @tsialex) for pointing out the edge cases where people need to have vintage systems to run vintage software.

For people who want the current, updated, secure Apple OSX - the expiration date on the cMP is here. Heroic efforts to work around Apple's attempts to block installation on a cMP will be worthless if the AVX compiler option is turned on.
 
I live in NC, I wouldn’t be advertising in Seattle’s Craigslist.

I won’t be selling mine even when I get a 7,1.
Ha - I wasn't even thinking about you, but now - well, I don't know. Just kidding ;) It doesn't matter, if I was buying I would rather get it from somebody from this forum who knows what he's doing. That's a nice machine.
 
It's relevant to @AidenShaw post, since if you are in the market for a Mac Pro 5,1 today, you are not really thinking with future software support.
I disagree. I think the 4,1 and 5,1 Mac Pros have been so popular because they can run the latest software and, once Catalina is released, they'll become less popular (like the 1,1 - 3,1's did once they lost OS support). It is this user population to which I believe AdienShaw's comments were intended. Not people buying older systems to run period specific software on them (I just purchased a PowerMac 7300 to run some period specific software and I don't believe that indicates PowerMac 7300 have a future).
 
The real fire sale will start when Apple makes a tiny change to the build files for Catalina, and starts to optimize for AVX.

With one minor change, it will become next to impossible to run Catalina on a cMP.
 
....Everything else is secondary to ProTools and don't matter.

Then you remember the days of going to a studio and seeing the very expensive SSL and Neve boards. When you look around the room for the computer it was mostly always an out of date Mac! But, of course there, it was all about the sound coming back over those NS10M's and huge speakers in the wall! :p

Hello Sound Castle! Hello Cherokee! Etc if you all are still around!
 
FYI that was my Mac Pro and I changed my mind, sorry if you sent me an email and I didn’t reply.

I will at least ride out until Catalina goes public to see if we are still running with updates.

LOL’ed when I saw this posted today, especially this part:

must be microsoft employes upgrading :D

California may have some good deals going

Don’t think I’ll have a better Gaming Mac until Thunderbolt 4 or someone comes up with some thunderbolt link aggregation.

But also I love the cMP platform so hopefully we can keep it going for quite a bit longer without adding kexts.

use one as a computer case for a PC?

Several years back, I sold a dual processor G5 I had laying around to a guy doing just that. He said he found himself in need of a Windows machine, but he couldn't bring himself to look at one in his home office. I think, at the time, there was even a program that made the Windows desktop look like a OSX desktop. I got fifty bucks for it on Craigslist.
