I just upgraded my duel core to a higher deul core and all I had to do
was flash the bios on my motherboard to accept teh new cpu. For ASUS
motherboards, it was a snap. Get up with you motherboaqrd manufacturere
and see what they have to say.

Good luck!

Going from a dual core CPU to a quad on the same motherboard
does not require a reinstall as Windows already has a multiprocessor
hardware abstraction layer (HAL) installed. The requirement for a
repair or full reinstall occurs when going from a uniprocessor HAL
to a multiprocessor HAL to support upgrading from a single core CPU
to a multicore CPU.

The only exception is when upgrading from a single core P4 with
HT to a multicore CPU, because a multiprocessor HAL would
already be installed for the HT.
