Hi everybody. I read a lot of info about that but can't seem to find an answer. I am interested in video editing (Adobe Premiere, After Effects, Sony Vegas and other) and was wondering whether investing in a professional (workstation) card (such as FireGL or Quadro) will accelerate the rendering process in the above programs? I know that a workstation card greatly improves wireframe editing in CAD programs, and that is good since I deal with 3DS Max too, but what about High definition video editing/ rendering? At the moment I am torn between ATI Radeon HD 4850, ATI FireGL 5600 and some other alternatives...
Also- when it comes to video editing software (rendering scenes) is the CPU still much more important than the GPU or a FireGL will make a big difference when rendering? I ask because I know in Premiere we have the option to turn on "Accelerate GPU rendering".

Any suggestions?
Thank you and have a nice evening.
