Hello everyone. Guys I need your advice. I want to buy a new card and which is better for Houdini: Nvidia Quadro 4000 or Ati FirePro V7900 ?
Also i saw one topic here about this cards: http://www.vizworld.com/2011/06/benchmarking-amd-firepro-v7900-nvidia-quadro-4000-catia/ [vizworld.com]

FirePro cards do typically offer slightly better performance in OpenCL so that would matter a lot in 3D/particle effects.
The other thing of note is that the V7900 supports up to 4 simultaneous HD displays (using Eyefinity) which can be pretty useful for compositing and fx workflows.
