Doubt you will improve on this at all with any other grahpics card...
wouldn't waste your money on a graphics card update for a 1,1 or 2,1 MacPro...

Best combination at the moment seems to be a 5,1 MacPro with OS 10.8.4 with a GTX680 (mac Edition) using ProRes LT or Proxy codec content
(Other PC edition cards also work - only with 10.8.4 - but at your risk...)
NOTE - 10.8.4 only works on a MacPro 3,1 or above...

I have been testing 10.8.4 on different machines and have had some odd things come up. Weird screen tearing and gui rendering issues for one... but the interesting one is that ML videos arent played back at their correct speed if they are just freerun in catalyst. I have been able to duplicate this on several machines. Simple changing the OS back to SL resolves issues.. all other things are equal... quadruple checked... this has caused quite some headache... is there a fix for this I dont know about.. I am about to start a large tour and would like to be able to run ML so I can use 680 vid card? Please help
