would you agree? and which graphics card would you choose? we don't want to spend £1000s (if we can avoid it) but we need this system to work and play hd video as it was designed.... we have the 32 later/16 mix catalyst running on a 64 bit 8 core macpro workstation...

at the moment we can play one layer of hd video without dropping frames...


if you need any more info please let me know..
you want it to work - today - you have to get nVidia card
gt120 cheap - doesnt have hidef playback problem - not good with triple heads - big screens
quadro 4000 - very new - 800GBP to 800USD - too new to have much info - but doesnt have hidef problem
gtx 285 for mac - from eBay at your own risk
