Basically the same as always. Gtx 970 is better in some games and the r9 290x is better in some games. I also bet in some of these, NVIDIA proprietary software was enabled such as FXAA and such. Which can decrease performance on AMD hardware in some scenarios. I would pick either one though, depending on whether you can get one cheaper than the other. Both good. Usually though, you can get an AMD graphics card that performs as good as an nvidia graphics card which is more expensive. I looked around and between these GPUs that isn't the case. Only seems relevant with the some of the other graphics cards.
