So I recently purchased a gtx 780 SC with the intention of gaming and doing 3d modeling work and game development with maya/blender/unreal engine 4. Originally, I was thinking of starting with the 780 and maybe a little later get the mid range quadro k4000 to use specifically for the 3d modeling work. I was wondering if just purchasing a GTX titan black with its double precision floating point performance would be a better option? Doing this would be around 100-150 cheaper and I would be able to game and do 3d modeling work with one card. I guess my main question is does the titan black compare with the quadro card mentioned above in terms of 3d modeling? Wasn't sure how much the titan black's double precision float performance means for applications like these. I know the K4000 is a mid-ranged card so I wasn't sure if the titan maybe would do even a little better than the k4000? Any help appreciated.
