Annie, i noticed that you're planning to use Win98 on your new build. I would strongly recommend you install either WinXP or W2K; they are far superior in terms of resource and memory management. Especially if you decide to add more RAM in your system, you will get much better performance w/ an NT-based OS.

I was searching for this particular cpu, and it's almost impossible to find. so i was wondering if my motherboard would be compatible with the same setup except it has 128kb cache...also, how much of a difference would this make??
More than likely it's saying that is the maximum (speed) of the CPU your MB will accept. So as long as you don't exceed those specs, you will be OK.
Typically, when vendors list the CPU specs, they will specify whether they are talking about L1 (level 1) or L2 (level 2) cache. In this case, since they don't specify, I'm assuming 512 KB is the L2 cache. Jumping from 128 KB to 512 KB will make a significant improvement especially if you plan on doing alot of video editing as you say.
Dont' know how much you're spending for your P4 chip, but newegg.com has some nice deals going on right now for P4 chips w/ better specs. They are a top-notch vendor w/ a good reputation.
