My goal is better rendering and less lag when working with high poly models in Blender and Zbrush and working in the Unreal Engine. My question is which would be better for this goal, a high end Quadro card, or a Titan card? Price is not a concern, my objective is the best performance. I also ask this because in an older system, Blender could render about 150 frames with a Quadro FX 3450, but when I put in a nice Radeon R9 280X, I couldn't get past 5 frames.
