CPU horsepower vs. memory bandwidth?

Which is more important for a video editing computer, maximal cpu power (e. g. overclocking a P4 3.0c to fsb250 with 2 x 512 MB premium meory) or maximal amounts of memory (4 x 512 MB value ram, with cpu and memory both at fsb 200)?

the best solution is both. Rather then max out one or the other, step up both if you can. I do not like running with less than a full GB of RAM, and we are now putting 2GB in all our DIY machines.

If you have a computer already, running less than a GB of RAM, adding more RAM is the #1 recommendation for upgrading and better performance.

More memory, but faster disc I/O is usually the real limiting factor. Video requires massive disc transfers, so faster discs help. RAID sounds good, but really doesn't help much, as any single drive is more than fast enough for video editing. The trick is to read from one drive/channel and write to a different drive/channel, which is why Matrox recommends a three-drive system: boot, video, export.

What type of performance gains could I expect to see (video editing) when jumping from 1 GB to 2 GB RAM?

Also, what difference would overclocking my P4 3.0c to ~ 3.5 or 3.6 gHz make? (fsb also increased from 200 to ~240, with 2 x 512MB RAM)?
