Alright, after a couple of searchs I think I pretty much found which kind of Graphic Card I need. I'm actually woking in 3D with Maya 2013 on BootCamp on a 4.1 Mac Pro/32 GB of RAM with the acual Graphic Card: GetForce GT 120 512 MB. I'm looking for faster renders and was wondering about which Graphic Card should be the best at the moment. Here's some of my questions about it: 1.Will I need to update to Montain Lion to install these (I'm actually with Snow Leopard)? 2.Considering I'll probably buy the next Mac Pro when it'll be out, should I spend $2300 for a Graphic Card or should I go for the $1000 one. 3.In the line of the previous question, I really don't know the Graphic Cards market, so is the prices drop are usual or it'll stick to $2300 for long time? 4.Also, I saw some topics saying the Quadro FX 4800 seemd to disapoint and that the FX 4000 was better. Considering the specs etc, the FX 4800 looks better to me, what's the deal between these 2? 5. I know the next Mac Pro isn't out yet, but considering your knowledge, is these Graphics Cards should works on the next Mac Pro? Thanks for the help in advance!
