I have the original macbook unibody core 2 duo 2.0ghz, 160gb 5400 RPM HD, 2 GB RAM I started editing HD video recently (1080P AVCHD) on my macbook in Final Cut Express. It is completely workable and I had no problem editing a 3 minute video including keying, filters, etc. I'm about to move on to editing 10-20 minute videos and I know that this is going to take much more time and I was trying to figure out the best way to cut some of the time rendering and "writing video down." I'm not expecting miracles, I have about $200 I could put into it, and I am trying to decide how much difference the following would make: 2GB of RAM -> 4GB 5400 RPM HD -> 7200 RPM (possibly a 2nd HD in the DVD bay that would just be a scratch disk for video) or 5400 RPM HD -> Smaller SSD Once again - not looking for hours off my rendering time, just possibly 10-15% performance gains in the area of "writing to video" mostly. Does anyone have any experience or knowledge as to what would provide the greatest benefit? Thanks guys.
