I went from a 2008 to a 2009. The performance when I got a second card (I only tested with GTX285 on the 2008) was an incredible boost. I have a 2K 50fps RED RAW here of an explosion I’m making a ‘day for night’ out of. I have 13 nodes (!!!) and I can still get real-time playback in quarter and half res… Is that insane or WHAT?
My setup is
Mac Pro 2009 2.26GHz, 6GB RAM
GT120+GTX285
Decklink HD Extreme 3D
RocketRAID eSATA controller with 4TB RAID0 spanned over four disks.
Not the wildest setup, but for my range of clients (for now..) it’s a massive upgrade from the Color workflow.
