I'm wondering what kind of performance increase I can get by overclocking my PII 450. I have an ASUS P2B-L motherboard. The CPU has the out-of-box fan on it. What kind of cooling upgrade can/should I get? I'm pretty sure my motherboard has a plug for some sort of thermal heat monitor or something. What kind of success/failure have you all experienced?

Also, what kind of impact does this have on video cards and RAM. Do you change the multiplier or the bus speed or both? If you change the bus speed from 100MHz to whatever, how does that impact the RAM and video? Don't they rely on the bus speed too? Thanks!
