I want to speed up the overall performance of my system with minimal cost and I am thinking that possibly upgrading the CPU will help. My system is currently a Pr 2.4 533 FSB with 1 GB of DDR333 or 400 on an ASUS P4P800 mobo. Windows XP. Radeon 9800 Pro and 2 HDD's, both IDE's. Can I upgrade to a P4 3.0E and will I notice?
