Thanks for the fast response.
Yeah, Ill be using this computer to run Pro Tools work and some Premiere / Final Cut work, possible a BootCamp partition for FL Studio.
Interesting how a modern chip would be more powerful than duel Xeons. I guess its not really worth it? Novelty wish.. eh
I was concerned that older architecture would hold me back but it sounds good to be reassured that PCI 2.0 isn't a limiting factor. So it seems older chipsets are a bigger bottle neck than most? I was aiming for a 2010 Mac Pro for the most part, I think those were Sandy or Ivy?
Another thing was that I plan to have this build for a while so I wanted to get the most for my money. I'll probably buy the lowest spec build and throw better hardware on it. How well did your MPro hold up?
I have no complaints with my Mac Pro; this 5,1 is performing like a champ for what I need it to do (After Effects, Photoshop, some Cinema 4D, Final Cut, and Indesign, plus Dota 2, Minecraft, and a few other games.) I upgraded the processor to a W3680 Westmere, bumped the RAM to 24GB, and swapped in the Radeon 7950 I previously had in my 2008 Mac. If I wanted faster performance I could get PCIe storage, but the Samsung 840 running in my SATA II bay is fine for me. I've got a Lacie 16TB RAID attached via USB3 for my long-term storage, and then a scratch HDD in one bay and a hard drive clone in another.
While new computers are certainly faster, it's worth pointing out that chip speed gains in terms of real world speed are not that impressive in the past few years, and multithreaded performance still tilts heavily to the 6,8+ cores you can get these on these machines (AFAIK Pro Tools is very good about using multiple cores, although with the limitation some plugins and VIs you have might be bound to a single thread). So they are still very viable machines for many use cases and will continue to be for a bit longer, especially if you're willing to do upgrades.
You can't, the CPU/GPU chips are soldered directly onto one of the motherboard. It's impossible to do for the end customer. But for Apple themselves it should be an easy job.
Nothing in the new Mac Pro is soldered; it's a bit trickier than the 2009/2010 Pros but if you want to swap the processor yourself you can do it. The downside is that the Ivy Bridge EP were the last of their socket type, so even if the software theoretically could support you swapping in a newer Xeon the physical connections aren't compatible. Upgrading RAM is even easier than the previous Pros.
The downside is the GPUs themselves are easy to upgrade, but there's nothing to actually
upgrade them to—Apple hasn't offered any upgrade kits, so basically if you have a D300 the best you can do is upgrade to a D700 by buying them off eBay. It doesn't seem like Apple's interested in such aftermarket upgrade options these days, but we'll see. The GPU is really the biggest knock against the new designs in terms of long-term viability; as much as people gripe about internal storage and expansion slots it's not really that much of an issue for me, but it would be nice to have the option to upgrade later on so I'm not spending as much on the front end. As it is unless I'm going to run games in Windows, the D700s in the new Mac Pro would cost me $1000 but wouldn't be much better than my $250 (when I bought it) 7950. So it makes very little sense to upgrade from my current rig.
And yeah, it does seem odd to me they don't do the very minor updates necessary for new revisions of the product, but then again they're only behind one chip generation (although the GPUs again are based on designs from 2011 and are thus the most aged element of the new machines.)
With Broadwell-EP seeming very iffy and the promise of Thunderbolt 3 and even true external GPU support, it might make more sense for Apple to bite the bullet and wait to release a truly next-gen Mac Pro. But if the wait is gonna' be another 18 months or two years, why not just release a minor update and show consumers that you're interested in the platform?
