CUDA: 3ds Max + iray Renderer
Nvidia's GeForce GTX Titan leads in our CUDA-accelerated 3ds Max + iray benchmark, followed by the GeForce GTX 580. Given GK104's poor compute performance, it's hardly surprising to see GeForce GTX 680 last in line (aside from the Core i7-3770K, of course). After a number of issues getting CUDA support working after Titan launched, the current drivers cooperate nicely. The hardware is detected and utilized without a problem.
