editing machine question

[videoconfused]

I'm going to be using canpous 100 for video cap. I already have one machine handy for encoding. I'm thinking of getting another machine just for capturing and some light editing. I was thinking about getting a celeron 2 ghz + since they are very cheap. And what I'm wondering is this:

1.) would a celeron 2 ghz or up be fast enough for capturing video from canpous 100?

2.) for light editing how slow would a celeron 2 ghz be? especially if i wanted to see a preview of it? ex. real time preview before it got fully rendered.

3.) how long would light rendering take on a celeron 2 ghz or up?

If someone can shed some numbers that would be great

Thanks

Here is this slowest machine I have tried to use with a analog to DV encoder:

Toshiba Portege 3010CT laptop with a P266Mhz processor and external firewire hard drive. This works great with DVio as the transfer application. No preview, but who cares? Never one dropped frame using this setup. With many hours worth of video transfered to DV. Now I wouldn't try doing any heavy editing or mpeg encoding with such a lowly beast, but for simple transfers to a hard drive it works great! You could probably use a P166 and achieve the same results.
