I just upgraded my Mac Pro (8 core, 2.93 GHz) from a GTX 680 Mac Edition to a GTX 980 Ti from MacVidCards. I was expecting a big boost in video power, but I can't tell any difference. I tried to run some tests. With NovaBench the 680 got a score of 188 and the 980 scored 178. With Cinebench R15 the 680 scored 48.58 in the OpenGL test, while the 980 scored 43.11. I play ESO and I have not noticed any big improvement in the frame rate. I am using the latest NVIDIA driver. I seems I wasted almost $900. Is there some trick I am missing or is this typical?
