Item has been sold, thanks for looking!

2 x Xeon "Clovertown" X5355 2.66GHz SLAC4 Quad-Core CPUs - $400 (+ shipping)

Had these in my MacPro1,1 as replacements for the stock dual-core CPUs and they worked perfectly. Only selling them because I replaced them with 3 GHz X5365 models. I think the price is reasonable considering what's out there on eBay (plus crazy shipping, customs, etc, etc.) but PM me if you have a fair offer :)

Should you be interested check out this thread (http://www.ehmac.ca/mac-masters/92461-upgrading-cpu-mac-pro-1-1-a.html) for a lot of great info on this type of upgrade.
