I have Mac Pro 2009s and 2008s and right now in the 2009 I have dual (x2) ATI radeon HD 5770s which are pretty solid , no issues but there isn't much CUDA and openGL/CL support (?) if I am not mistaken? Which would you use for your personal main workstation machine? I run a lot of high end applications like DaVinci Resolve , After Effects, Cinema 4D, Premiere Pro etc. Can anyone give me some insight on how you would utilize these cards? Is it an idiotic idea to think about using a Quadro FX 5600 AND 1 ATI Radeon 5770 in one machine? --- OR should I just use the Nvidia Quadro FX5600 for my personal 2009 mac pro workstation and then put the dual Radeon 5770s in the second best mac pro workstation I have ? Thanks!
