No Thunderbolt, though. Not in any of the old form factor Mac Pros. That's what is most likely to end their OS support eventually, in my opinion.
I don't think support for the 2008 will be dropped any time soon. There is no natural reason why that would happen (it's got EFI64, and it's 64 bit.)
You are betting that AMD folds ? Not particularly likely. Even less so since Intel's extra payments to Nvidia are drying up ( so they could "throw money" as problems ) and the classic PC form factor market stagnates.
BS fanboy mode is highly unlikely to provide clarity of insight into the future. If Nvidia gets their OpenCL act together they have a shot at being in a future Mac Pro, but as of right now they are behind the curve.
You should be far more deeply concerned about what happens to the dGPU market for the older Mac Pros. If that stagnates or collapses the value of having dGPU replacement capability is going to go down. (the Hackinstosh market will be around but it isn't going to be effective in keeping prices up. If counting on hacked firmware to keep Mac Pro prices up... LOL... betting on the wrong horse. )
Some (probably most) of the effort to leverage the extended time the 2012 model was primary Mac Pro model by dGPU vendors should have largely petered out in 2-3 years. When the 2008 goes into vintage mode even more so. ( Population of active box-with-slot Mac Pros looking for dGPUs is going to tick down substantially).
Well, all that's assuming the slotless nMP, and the modular, 3rd party Thunderbolt concept that comes with it , will become a success .
Or even be a viable option in the workstation market .
And time is not on Apple's side in this market, which demands workable and competitive solutions now .
Well, the question was price, not usage.
We have documented over at Netkas that both AMD and Nvidia cards are running VERY poorly in 3,1 machines. As in Unigine Valley scores that are 60% of what they would achieve in 4,1/5,1 with 7950/70. The real kick in the nxxs is that the 1,1 isn't affected.
EDIT: GOOD NEWS EVERYONE !!! A guy in the 3DMark thread just told me that my 2009 8 Core is worth $4K !!!
So I guess our worries about sliding prices are over.
Wow, it's APPRECIATED in value since I bought it...AMAZING !!!!!
I don't know what's going on with the driver stack that's making that happen though. But I think it's probably incompetence over conspiracy.
Hey MacVidCards,Will be fun as 5690s come down out of stratosphere, everyone will have 12 core 3.46 Ghz with a Titan Black or two.
Looks like Wireless AC is going to work too.
Still good times ahead for cMP. Obviously the 2009-12 Dual Core machines will hold value better than 2006-2008 and 2009-2012 Singles.
With the SATA2 limit you mentioned limiting SSD upgrades, I would guess that it won't be worth too much. $1000 would probably be fair, if that.
The problem is that it's a pro machine that won't really be usable as a pro machine at that point.
12-core cMP is still a nice machine but they will follow the fate of 1,1s too. I cannot imagine not even a prosumer/up-and-coming pro using a machine with SATAII and USB2. new software will probably take advantage of GPUs and bandwith in nMP.
As someone else stated before - the prices are probably inflated right now. Once the new machines get solid foothold (less than a year I guess), all those "valuable" MPs (2009 and newer) will drop to 500-1000 range, the same where 1,1s, 2,1s and 3,1s are right now.
