Hi folks, I've been searching the pages for a while and couldn't find anything that answered this so hope I'm not creating a duplicate thread. I'm running a iMac 3.06Ghz, the October '09 model. The graphics card is the NVIDIA GeForce 9400M with 256MB of shared DDR3 memory, I know that Final Cut Studio 3 prefers 128MB of dedicated graphics but also know that you can work around this, but Colour and Motion may run a bit slower. My main question is, if I upgrade the internal RAM from 4GB to 8GB (or even 16GB) will this get around it? I've worked in Final Cut Studio 1 for 3 years now (hung on till the old MacBook Pro couldn't take anymore), and I'm very familiar with the editing side of things but I don't really understand what effect the graphics card will have or what the RAM will effect. Obviously I know the greater the better but if someone could answer this whilst explaining that I'd be greatly appreciated.
