I need some advice on which to buy. I use Final Cut Express currently. I would like to start editing longer movies soon (Does that cause problems on express??). At this point I have a Powermac G5 and as much as I hate to say it, I need to upgrade soon (Intel, Need Adobe CS5). I would prefer iMac price over Mac Pro so can I get by with going the cheaper route? Please help... oh and by the way, please explain as if I know nothing 😀 (please try not to abbreviate the technical stuff)
