Worthwhile to upgrade from PII 300MHz to Celeron 533MHz?

[charvey]

I've kept the Task Manager screen open while running different applications to see where an upgrade might be needed. CPU usage pegs at 100% when I play a CD while doing anything else. Problem is, I don't know what to upgrade. Mobo will support a Celeron 533MHz. Is this a worthwhile upgrade?
P.S.- If so, could someone explain where the required converter card with voltage control needs to go?
Thanks for the help...Ken

You'd be wasting money.
