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? 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.
