So when I got my new Mac Pro and saw the announcement for the Nvidia Quadro 4000 I thought this was going to be the moment to switch from FCP to Premiere pro and go Cuda crazy! So got a loaded Mac Pro with 32GB and 4 2TB Caviar Black drives and the Nvidia Quadro 4000. It is a bit noisy compared tot he nice and quiet Ati 5770, reminds me of my old 8800GT at startup. Already had some weird issues with the display after leaving it render some After Effect stuff. It actually freaked out on a java script when I tried to order a bunch of blurays on play.com. Will attach a screenshot: http://nerdo.net/Quadrofreak_2010-12-17.jpg cinebench results for this system: Cinebench 11.5: OpenCL: FPS: 21.67 CPU: 8.62 Not bad but not what I expected, Premiere Pro is OK but it is not the real time miracle with Canon video I was hoping for. Media compressing in the right format: H264 with the Adobe media encoder was a big shock: at last I got all the way up to using 94% CPU or 1400% CPu as the activity monitor calls it. 64Bit software is definitely big fun. Upgraded all my Magic Bullet plugins to the CS5 versions and at last: Looks without rendering, not a full frame realtime playback but decent previews. Some tweaking seems to be in order.
