I think you need Xeon due firmware limitations.

Seconded. I've read bits and pieces online; the i7 causes sleep mode problems, amongst other things...

A shame given the cost, but it's a Xeon and I'm surprised people got the w3580 to work... :D Wish I had $1000 right now, but mastercard needs to be paid first...

The Xeon W3570 is out now, though probably in limited supply. It is a 3.2GHz processor that you should be able to get for $600. I really wouldn't count on the Core i9s working in the current Mac Pros.

Would W3570 work? Is the upgrade process similar to the one in a PC?

Sorry I've confused myself (easy to do with Intel's code numbers and some incorrect reporting). The i7 960 has just come out which is 3.2GHz, the xeon at the $562 ($600 retail) price range tops out at 3.06Ghz (W3550). This may change soon to match the Core i7 range as they usually are identical. There is a spot for a $562 W3560 at the same 3.2GHz speed as the $999 W3570.

Yes and yes to your questions. There are threads on here that have photoguides to upgrading processors.

1. Yes, you can use the i7 parts in that system. Search MR, and you'll see a few people that have done it. :)

2. The i9's can fit the socket, but Apple won't update the firmware with microcode for those parts. You could try it, but I wouldn't be surprised if it didn't work. :(

3. You can use the Xeon equivalents if you wish. They do use less power, and would retain the ECC functionality if you want/need it. The consumer models don't have ECC enabled (disabled during production), so if you use them, you will lose that feature. But memory should be easier to find, and less expensive, as you'd no longer be required to get UDIMM's.

I run a i7 975 without one issue. Not sure why there were problems reported. My system wakes and sleeps without a hitch.

Nice to hear, thanks! I might go that route then since I've spent more on replacement 3D rendering and other apps lately... (did you have to replace the RAM at the same time? )

I upgraded to 4x4GB.

FYI. The W3580 @ goes for about the same price on EBAY. Ive seen them go for 700-800 at times. Just search and you will find. They are the same part but support ECC.

I picked up my i7 975 for 750+ shipping. It was a tray CPU.
