Everything I've been hearing about CS5 has been incredibly positive. I'm
really looking forward to working with it. From all accounts (on the boards
at least), its raised the bar for NLEs.
P.
CS5 Mercury Playback Engine on Snow Leopard in 64-bit and a NVIDIA Quadro FX 4800 ($1500) is pretty impressive, particularly in a mixed format, native timeline.
I wish there were less expensive qualified Mac NVIDIA cards, but with this setup on a multithreaded MacPro, it doesn't get much better.
Apple are you listening?
