What is the best CPU upgrade for a Mac Pro 4.1 2009 Quad 2.66 ?

[Flocarino]

I just got today a Mac Pro 2009 (4.1) Single CPU Quad Core 2.66Ghz and I would like to know which is the best/newest/fastest processor that I can drop in as an upgrade?
I'm looking for hours on the net but I can't get an exact answer for this exact model(early 2009).
I've seen something about the W3690 but I'm not sure at all, so please help
Thank you in advance!

the most cost effective is a w3680 3.33 hex. around 600

sellers on ebay

it is a bit harder to do with the 2.66 2009 quad as you need to do an efi update


this shows how to do it with a 2010 but there is a link on how do the efi for your year.

Thanks Philip, so the W3690 is a NO, right?
What about the EFI update, I haven't seen anything about this anywhere, just straight CPU replacements!!!

you can do the w3690 it costs 1000 for a new one. it is the fastest. There is a link on how to change your 2009's efi.

You can drop in a W3580 3.33GHz 4-core no issues. These are very hard to find and will cost you over $1,000.

Or you can upgrade the firmware to a 2010 that I'm sure is not authorized by Apple: http://forum.netkas.org/index.php/topic,852.0.html

Now you can drop in a W3680 3.33 6-core and make it fly like a new machine. These CPU's can be purchased anyplace for $600.

Any Nehalem is drop in (Fastest 3.33GHz Quad). Any Westmere will need EFI update (Fastest 3.46GHz 6-core). The sweet price point is the W3670 3.2GHz 6-core @600.00 and W3680 @650.00. $350.00 more for 133MHz is a rip off but the bragging rights would be yours
