Where can I find this motherboard ?

I would like a new motherboard with the following criteria for use as a high end workstation running Photoshop -

1. Takes Pentium D (could consider a dual AMD solution if it meets the other criteria)
2. Has minimum 2 x PCI-X at 133MHz
3. Takes DDR2 at 533 or 667 and up to 4GB
4. Does not require ECC memory
5. Graphics is PCIe x 16

Thanks. I had actually found this board but it was the only one. In New Zealand it is available on special order and cost $550 (about USD380). I felt that this was a little expensive for what should be a far more common board. Or am I mistaken ?
I would have thought that far more people should be looking for something like this.

H'mm maybe the board isn't so expensive here then. I am mainly looking for a new board for my wife who is a heavy Photoshop user. With some of the things she does the fastest memory, disk access and processor speed she has results in much less time waiting for things to happen. I even use an Ultra320 SCSI disk for swap space. If you are serious about digital photography then this is what you need. I have seen work files of 400MB and print jobs 600MB in size. Storage is well over 400GB even after backups. Currently we both have XP2800+ systems with 1GB. During an evening she can end up waiting for an hour for various processing. However both system have lasted for well over 3 years so we have had our money from them. A dual Xeon system might perform slightly faster because of 2 seperate processors and cache but this might even be lost because of slower memory. Would cost more for possibly little gain.
I would class this as desktop use all-be-it heavy (it is a home PC after all). I suppose it comes down to semantics. I view a workstation as the front end to a weather forecasting system or use for serious modelling at a University.
I have to admit that since I own a computer sales and service company I probably have different ideas as to the best solution. I am definitely fed-up with my wife turning round to me and tapping her fingers on my desk while she is waiting for a response from her computer.

You're after Intel Socket 775, for Pentium D, with PCI-X right ?, and maybe Xeon with PCI-X ?

Yes. But if Xeon then PCI-X AND PCIe x 16 and preferably memory not ECC (bcause there is a 50% premium and it isn't required for a workstation).

For example, would something like: http://www.gigabyte.com.hr/Server/ [...] -4MXSV.htm ; suit your requirements ?

The GS-4MXSV has no PCIe x 16 only x8. And the PCI-X is only to 100MHz. I have looked at this board already and it is close.

Or is PCI-X not really a requirement ?, eg: Are you just after SATA RAID-0 with NCQ ? you could save alot of $$$ by just using Intel Matrix RAID onboard (can do RAID 0 and RAID 1 on seperate partitions over the same two HDDs. Very useful in your situation, and more cost effective than looking at mainboards with PCI-X slots).

I want PCI-X because you can plug in either (or both) SATA II raid boards that run at x8 speed of PCI bus and U320 64 bit boards to give SCSI a hurryup. Until motherboards and controller boards come out that have PCIe x 4 or 8 then PCI-X has the edge.

If so check out: http://www.giga-byte.com.au/Mother [...] et+775.htm ; then scroll all the way down to Intel i945, i955 and i975 series boards. The nForce 4 boards for Intel would also likely do what you want (but Intel Matrix RAID is likely more useful to you than the nVidia nForce feature set).

I want to use raid 10 on a 4 channel SATA II controller for max performance, redundancy and capacity.

PS: Just using Giga-byte as an example, but they are often underestimated and have more variety at the "prosumer / workstation" mainboard segment than Asus, MSI or other "extreme overclocker" style brands.

I am not interested in overclocking. I have enough problems keeping systems running with the software I load without complicating life
by overclocking.
