My father in law has a P4 3.0Ghz machine... we think it needs some upgrading...
As it's a 775 chip, can we upgrade to a Duo/Quad chip or are we stuck with a p4 type?
The MB is an MSI 945P Neo type deal, no worries if it can't happen, just don't want to upgrade the chip/ram and find out it's useless.
Thanks.
