I'm looking at building a system with dual quad-core processors i.e. 2 physical processors, each physical processor having 4 cores.  Will Windows XP Professional 32-bit detect and use all 8 cores?  What about Windows XP Professional 64-bit?  (I haven't decided yet whether to go with XP 32-bit or 64-bit - just don't know how good driver support would be)

Cool, thanks!  Do you have a preference between 32-bit vs 64-bit XP?  I've heard horror stories about going 64-bit due to lack of driver support, but don't know if it's really that bad or if it's just exagerated.

64 bit drivers can be an issue check first that you can get 64 bit drivers for all your hardware, 64bit is only worth it if you have more than 4Gb ram
