Okay, you might have guessed that I'm a Mac user.
My thoughts on what is the ultimate system within reasonable price range.
Excluding AVID DS Nitris and similar that can cost mortgages.
For my money a Mac G5 dual 2.5 liquid cooled processor with 8 Gigs of RAM, two internal 200 GB hard drives and another 2 external FireWire 250 GB hard drives, a Mackie audio mixer, Tannoy reveal active near field monitors (speakers) (because audio editing is more important than the images in my opinion).
Two Apple 22 inch Cinema HD displays, a Sony pro monitor with blue switch, a Neumann u87 mic for those VO jobs (with pop shield of course), Sony DSR11 DVCAM deck.
Now for the software:
Final Cut Pro HD, DVD Studio Pro 3, Shake (a must), Logic Pro, Photoshop 8, Toast, BitVice and Motion for when you want to play.
This little system is assuming you don't want to shoot uncompressed D9, HD, DigiBeta and the like, it is fine for MiniDV and DVCAM formats. If however you do need uncompressed then a Deckink card, a raid array and a few other bits will fit in nicely.
All the above will come in at around £12,000 or £15,000 for the uncompressed version.
Totally and utterly unbeatable for the money. So many Hollywood movies are coming out of this system now.
Go buy one today, you won't be dissapointed
