You must also consider this as well. XP doesn't support 4 cores yet. It might be taken care of when SP3 comes out but currently on Vista supports the full potential of a quad core. As far as which is better? On XP it really doesn't matter since there is only 2 cores being recognized.

Both XP 64 and 32 bit recognize and utilize quad core processors.

Currently it is only 2 cores. I had a feeling you were going to post something like that.

I am running Quad Core on both XP 32 and 64 Pro. Fully recognized and utilized.

I only wish for correct information to appear on this forum is why I replied.

Again both the Task Manager and Core Temp record all active use.

In a nutshell, here are the basics:
Both Windows XP Pro and Home [...] support both dual core and quad cores processors as long as they are on the same processors. There are no additional licensing fees per core. But when you have a system using two processors, only Windows XP Pro supports this function.
Microsoft states officially:
“Microsoft Windows XP Professional and Microsoft Windows XP Home are not affected by this policy as they are licensed per installation and not per processor. Windows XP Professional can support up to two processors regardless of the number of cores on the processor. Microsoft Windows XP Home supports one processor. “
