It's confusing but in reality it's 2 cpu's each with 2 cores, each core with
two logical processors. Microsoft has stated the license is for the number
of cpu's regardless of the number of cores or logical processors.

Windows XP Pro can only support 2, so you would need some thing like Server 2000/2003 to get the maximum performance out of your hardware (do note that windows servers only support 32 logical proccessors), unless you do the clever thing and switch to Linux/BSD (do note that, in theory, Linux/BSD supports an unlimited number of logical processors).

Hi Kerry.
May be we sould use correct terms.
In dual xeon setup board will contain 2 dual core xeons.
Each socket is one processor for the XP pro.
each processor contains 2 cores, so we have 2 socket*2 cores=4 cores.
If we enable HT, each core will have 2 logical 'cpu', so 4 cores * 2 = 8 'cpu'
so XP pro's task manager wil show 8 'cpu' .
