So at the moment, we can't even spec a nMP equivalent with as close to the same specs as possible.
Not if you want to build it yourself. I am going to check Dell/HP uk and so forth.

Perhaps a little more comparable PCIe

It is very difficult to make such a comparison between the nMP and other workstations because a lot of the cost is in the GPUs and much of what you pay for is in the drivers for the GPUs (the equivalent consumer cards are very similar hardware but much cheaper).
The nMP may not have the same drivers, I guess, available as the Windows cards containing the same chips. If that is the case (and I don't know if it is) then it might not be fair to equate the GPUs in the nMP with a fully supported professional card in a different workstation.
I think though you are correct about pricing if you rigidly try to match a pc workstation to the nMP. The key point though is that general workstations are much more flexible in their configuration and for applications not designed mainly for dual GPUs a pc workstation could be more powerful and cheaper.
Another issue is that Dell workstations (for example) are available at very large discounts which won't be true of the nMP. The Dell workstation I purchased 4 years ago was only 40% of its official list price (it was officially a refurb but was actually brandnew).
Apple's modus operandi is not necessarily to overcharge (except for upgrades), but to force users to buy features they would not have purchased if given the option.
AFAIK, most errors come from the backround radiation, which is usually very small. If you do not work on expensive projects, then ECC-RAM is not really necessary....
You can build a much cheaper desktop system if you go with i7 but then you lose ECC RAM. When you get up to 64 GB of RAM there is a greater frequency of errors with more RAM so it becomes more important to have error correcting.
AFAIK, most errors come from the backround radiation, which is usually very small. If you do not work on expensive projects, then ECC-RAM is not really necessary.
ECC protects against undetected data corruption, and is used in computers where such corruption is unacceptable, as with some scientific and financial computing applications and as file servers. ECC also reduces the number of crashes, particularly unacceptable in multi-user server applications and maximum-availability systems.
Most motherboards and many processors for less critical application are not designed to support ECC, for economy. Some such boards and processors are able to support unbuffered (not registered) ECC, but will also work with non-ECC memory; a BIOS setting enables ECC functionality if ECC RAM is fitted.
ECC memory costs more, as each bank requires 9 memory chips compared to 8 for non-ECC memory. In some cases the price ratio reduces to 9/8, as an example, on 2008/11/30, on Crucial.com, an ECC CL=5 unbuffered 2GB DDR2-667 DIMM cost $30 while the corresponding non-ECC part cost $28, a difference of 1/15, however some ECC modules cost twice as much as their non-ECC equivalents [Crucial CT12872Z40B and CT12864Z40B, Jan 2009]).[original research?] ECC-supporting motherboards, chipsets, and processors may also be more expensive.
ECC may lower memory performance by around 23 percent on some systems, depending on application and implementation, due to the additional time needed for ECC memory controllers to perform error checking.[19] However, modern systems integrate ECC testing into the CPU, generating no additional delay to memory accesses.[16][20]
Ultimately, there is a trade-off of a small number of instances of loss of data integrity and crashes against paying a higher premium.
I checked Dell uk for Precision workstations a month ago so go for HP!
With AppleCare the hardware is on a 3 year warranty so home built systems aren't really comparable if you are speccing workstations for business. AppleCare for the old Mac Pro tower is £199.

As I noted in this thread, homebuilt systems offer component warranties which mostly blow away Dell or Apple.
However I don't have the time, nor the inclination, to be own my PC support guy. I don't feel like building my own computer and replacing my own bits. I used to build my own computers in my teenager years. My time is too expensive and too precious for that now.
If you can figure out the HP UK website, then please let me know.![]()

Dell's support is also superior on their workstation products to Apples. It is frequently on-site, 3 years, etc.
Dell's support is top notch but Apples isn't that far behind with AppleCare. I've seen them come out next business day for 5,1's.
Fair enough... but his point was the warranty was longer/better. They are not comparable.
I'd argue getting a replacement hard drive from WD in 2 days or driving to the local computer store and picking up a replacement component is quicker than hauling your Mac Pro down to the Apple store (where they may not have the part) or waiting for Dell to come over.
If you live within 50 miles of an Apple store, they won't do on site.. Supposedly AppleCare will if you have their "business-level" service, which nobody has explained to me how one gets.

Try this - it's a US reseller site, but as close as I can find - http://dv411.com/hpz800.html

I emailed Falcon Northwest a couple days ago, they make custom built gaming rigs, to ask them if they could build something with as fast of a PCI-e SSD as the OCZ card. They had no PCI-e SSD options listed. I just got back this reply:
"We have offered/used that OCZ PCIe Revo Drive before; failure waiting to happen so we do not offer it anymore."
The best they offer is RAID0 SATA 3 which is 750MB/s max.
An unreliable OCZ card puts another damper on the build-your-own option over the nMP.
Build your own will have the option to install a PCIe Raid card to bring up the speed drastically, but unfortunately here lies the diversion in trying to compare the nMP vs. A Pro workstation with PCIe slots.
If you could install a RAID card that allows you to break the SATA 3 - 6 Gb/s transfer barrier (750MB/s), and then add enough SATA drives to bring you over 1250MB/s nMP speed, then I would consider that an acceptable comparison for this thread. The card would have to RAID across multiple SATA controllers, not just across multiple SATA ports run by the same limited 750MB/s controller. Would that allow you to beat the nMB's pricing with a machine of similar performance, or would the price still go over the nMP for all of the needed parts?
I have such a setup in my current 4,1 MP that uses 3 SSDs in RAID0 on a Highpoint x8 PCIe card to achieve 1GB/s read and 1.3GB/s writes... so it's certainly possible (link). The card/cables is around $200 and then you need at least three or four SSDs to get to those speeds so it's a minimum of $500-600. There's certainly nothing as elegant in a single slot solution in the sub-$1000 price range that can do that kind of speed.
Impressive, it's good to know that it "could" be done even if it does cost more, for those who prefer to build a box with internal expansion. I think the lack of ECC is what's ensuring that you can't just build a cheap i7 machine with everything the nMP has. If you want ECC then the supporting parts cost more, and I'm having a real problem convincing myself that I want to spend thousands of dollars on an important work machine that doesn't have ECC just to build it cheap. Random crashes are very frustrating even if they only happen once in a while.
It is. Primarily about reliability though, rather than purely for profit.Yeah, I suspect ECC is one of those things that motherboard vendors use to separate consumers from corporate (eg. small budgets from big budgets)I'm not sure what difference it makes to every day stability though.
