is xp pro capable of using quad core

[GS]

for power user with a lot of multi-tasking, will Xp Pro PC benefit from
using quad core like Intel core 2 quad Q6600?


what about an existing XP Pro PC with dual core cpu replaced by a new quad
core, does one have to do anything besides reactivating the XP?

If the applications you have will not utilize it - you won't notice too
much.

If you happen to have a motherboard that all you have to do is change CPUs -
you won't even have to probably run a repair installation and/or activate
again.

thanks , you are saying the XP OS will only be able use at most 2 cores
and that is the limitation of the OS?
OT: what is the limit of vista business edition?

No. Windows XP Professional will support two processors - the number of
cores are irrelevant...

The point is that certain applications are written specifically for two
cores or four cores. If you are running any applications that are
designed for a quad core, then you should notice better performance if
you upgrade to a quad core. And there may be a chance that multitasking
will be more efficient with more cores.

thanks, apparently some thread in technet hinted that the xp pro task
scheduler is not that great in spreading the load across multicore/cpu, XP
ro 64 and vista, w2003m w2008 are better at it


however different version of vista has varying degree of support for
multi-core it seems
