Please Help! I need quality advice about buying my new G5. Here's the deal-I somehow talked my dad into getting me a G5 for my graduation present and to seal the deal I need to figure out all the right components that I need and then give my dad a price and hope that he still says yes. I am a video editor and am looking to get programs such as final cut pro, avid express, and of course I want my G5 to be big enough, fast enough, etc. to be able to use these programs along with others such as photoshop, image ready, and dvd studio pro. So any and all advice that you folks out there have on what I need to be able to happily and easily use these programs would be much appreciated. Thanks! Stacy.
