Hello everyone. I am a new DVX user. My brother came back from college with one and he is letting me use it for my indie film stuff. I am used to using Sonys consumer mini dv stuff, so you can imagine my excitement over the DVX! This is more of a question about my computer. I am an imovie wizard by now and I am about to dive into FCP4 after reading a few books on it. I am not the most computer saavy person, so I was wondering what upgrades would be recommended on my single G4 500mhz 256K 20gig system in order to get FCP4 to function decently. I know I need some more RAM and a harddrive, but I'm sure there is a line between necessary and overkill. I would prefer to spend under $500 on the upgrades if possible. There is an Apple store near my house but I'm not sure if I could get the best deal on my new hardware there or online. I've done some research on other boards but I wanted to see what you guys had to say. Any help at all would be greatly appreciated. Thank You!
