I currently have an 2 x 2.8 GHz Quad-Core Intel Xeon (Early 2008) Mac Pro with which I have been editing with Final Cut Pro 7 on.
I wasn't really wanting to move to a laptop - I was hoping for new iMacs at WWDC 2012.
Waiting any longer is not something I can do at this point if I'm going to start this new project on a new system. However, after looking at Geekbench numbers comparing my current MacPro setup to the 27" current iMacs, I'm not seeing a huge increase in the numbers. Is this a realistic way for me to look at this? Should I not bother upgrading at all? Are there big benefits that I would get that Geekbench isn't showing me?
One thing I do know is that my current MacPro processors do not support Hyper-Threading or Turboboost or anything like that. Also, my graphics card is lacking GPU acceleration that many new apps take advantage of. Would these items alone be enough to justify an update when using Premiere Pro CS6, Photoshop, and After Effects?
Do you really need a MAC or would a PC be OK?
If you need a MAC, look at the latest MAC Pro, fully loaded with dual hexa cores, 64 GB memory, etc. It comes to around € 11,000. You still need a MAC Quadro 4000 card, because that is not included in the price. It is not latest technology and is significantly slower than a modern PC, but downgrading to a very slow iMAC or MBP that do not meet practical minimum requirements is even worse, especially for a feature length film.
If you go to PC, you have far more options for far less $$$ and have much better performance. See http://www.adkvideoediting.com/
I am assuming you want to buy a complete system, but if you want to build yourself, look at
