Just to let you know, this is a server chip hence the 604 PGA setup:http://ark.intel.com/Product.aspx?id=27088
Those are the technical specs.
Since it is on the 90nm process, it is a server processor based off of the Prescott core.
Now it does support 64bit but the CPU is from 2005 and you will have a damn hard time finding a mobo to support it that will have everything that a desktop board has such as PCIe, high definition sound and so on.
So in short, that CPU is not a good deal. It too old and probably wont perform anywhere near what you want compared to current day CPUs.
