You really have to check the specs out, for each model, as Nvidia jumped around a lot in memory bus. The GTX 260 mentioned has a 448 bit width bus, and really was an awesome card at the time for the price, and has held up fairly well. the 560ti and 570 class cards, had 320 bit wide memory bus. the 760 as mentioned has 256. But they went crazy in the 900 series cards, the 980 and 970 both only have a 256 bit bus, and the 960 is 128 bit, leaving hope they will come out with a 960ti or 965 with a 192 bit bus, or even 256 bit. As with any card, you really need to take a look at the review sites, and see the fps in games you want to play, and resolutions you want to play them in, and hopefully they do some of the benchmarking on systems that are more realistic. Just giving specs and benchmarks on an I7 top end model and 16 Gb DDR4 memory, and a top end SSD like a Samsung 850 Pro, is not very helpful to someone who is running a 4 year old I5 and 8GB of DDR3 and a mechanical hdd running 7200 rpm.
