Hello macRumors. I am a Maya artist working on a dual quad core 3.2 ghz Mac Pro (early 2008). My Quadro FX 5600 just died on me and I need a replacement pronto. After Googling the subject, I learned of the Radeon Hd5870 Pcie 2048mb. Product # 5870PE52G. Does anyone have any experience with this hardware config? Note it is the 2 gig version of this card. Is there a newer (or any) alternative that google isn't telling me about? My homeowners insurance is paying to replace the Quadro, so cost is trivial. I use two screens for Maya/Zbrush work, and a splitter to pipe the second screens' signal to my home theater for video viewing/gaming. All opinions are welcome. Thanks for your time.
