I graduate in about 2 months, and i won't need portability so i'm considering selling my pristine 15" PowerBook to pay a big chunk off a refurbished G5 PowerMac. My dilemma is that i don't know if it is best to get a 2.5 / 2.7 Dual Processor or a 2.3 Dual Core. I know the Dual Core can address 16GB of RAM, but i'll probably never go over 4 - 6 GB. Anymore than that and it'll cost more than a new PowerMac. I don't require the cutting edge of technology, but i would like the machine to last me a good 3 - 4 years. I am a filmmaker/video artist, but don't use any special effects, and i don't use HD. I am quite comfortable with DV for a couple more years at least. Does anyone know which machine is my best option, which will bring me the best performance for my money ? Thanks in advance, i value everyones' opinion. Rich.
