The GTX 950 is Nvidia's latest Maxwell card which is based on a GTX 960 but with 25% fewer CUDA cores and 25% fewer texture units. Comparing the GTX 960 and 950 shows that, as expected, effective speed has been reduced by 25%. The GTX 950 is positioned above GTX 750 Ti which is Nvidia's energy efficient mass market GPU. Comparing the 750 Ti and 950 shows that 950 is nearly 50% faster but it's also priced 50% higher so the 950 doesn't offer improved value for money. Gaming performance for the GTX 950 at resolutions up to 1080p on high/ultra settings will be satisfactory most of the time. That said, the GTX 950 is priced on the high side ($160). At present the GTX 960 ($171) offers 25% better performance for just 7% more money. See a current list of the best value graphics cards here. [Aug '15 GPUPro]
