Are there still some goof balls actually buying these things?
I purchased a Mac Pro 6,1 new from Apple directly two weeks ago!
As outdated as the D700s are, they still out perform the best supported nVidia option (titan-x maxwell) in my use. Also, as outdated as the 12-core Xeon E5-2697 v2 is, it still performs extremely well - for what I do anyways. That AND, RAID and outboard rec.2020 video boards over TB2 work as well as needed.
While the D700/1TB/12-core works extremely well, the lower variations perform quite poorly - I'm looking at you D300 and D500!
While I appreciate Apple has silently upgraded the internals since launch (1TB SSD is 50% faster), they really should offer a offer a GPU upgrade program. It's painstaking how gimped the D300 is. And if you end up with a nMP w/ the dreaded D300 or a shoddy D500, all you can do is sell the whole Mac on eBay and buy another one with D700s installed!
Am I extremely pissed Apple has all but divorced itself from the Mac Pro? A Big F'n YES!
As "interesting" as the Mac Pro is, it is a perfect example of Apple's dilemma, especially post Jobs - they refuse to make what "we want" or address "our needs".
All we want/need is another big cheesegrater, w/ dual sockets, plenty of room for full length cards, and tons of internal drives - all running OSX.
Instead Apple gave us a "spaghetti" mess of wires running everywhere, and when the pros complained they couldn't put their expensive PCIe cards in it, they all but buried the Mac Pro - then shuttered the automation "pro" team, eliminated the dedicated OSX team by merging it with the iOS team, and renamed OSX to maxOS.
Courage, truly.
To deal with the problem Apple created, I basically built a "wind tunnel shelf", that hides the entire mess and keeps everything at safe operating temps. (actually got a 5-10% performance increase with the tunnel shelf).
So instead of a brilliant shiny thing of awesome on my desk as Apple engineers foolishly envisioned, my mac pro is completely hidden from view.
Clearly (I say sarcastically), Apple has learned from the trashcan experience. This time they're going to take the best Desktop in the world, paint it black, remove an "i" and add "pro" to the end of it.
