I have an old Power Mac G4 right now, and have been doing some video work. I currently have been doing the video with Final Cut Express in my MacBook 2GHz with 2GB of RAM, and I find it suffices OK with my needs. But we (at work) want to have a computer that can be available always. So I am wanting to find out if the Power Mac would be enough for this. I could update the RAM to 1.5GB and put Tiger in it. And maybe upgrade the processor to a 1.2 GHz. But I want to know if the update is worth it, would it be the same as in my MacBook or would it be much slower than it? Any ideas?
