Just because the 780 has more cuda cores doesn't mean it's stronger tho. After reading a bit online the lesser cuda cores out perform the 780's cuda core when tested. The 970 is amazing! Higher overclock room and less power usage which mean less heat.
I haven't heard any issues regarding the 900 series, they are based on Maxwell and best architecture in my opinion. They also bring tons of new features for better gaming performance. Drivers won't be an issues its NVIDA they are quick on updating there drivers when issues arise.
I'm currently selling my EVGA 780 SC 6GB on Ebay since for the price I can almost get two 970 and that's what I plan on doing.
The GTX 970 has a 173 MHz higher core clock speed than the GTX 780, but the GTX 780 has 88 more Texture Mapping Units than the GTX 970. As a result, the GTX 780 exhibits a 67.1 GTexel/s better Texture Fill Rate than the GTX 970. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 EVGA SC w/ ACX 6GB Edition are marginally better than the GTX 970.

The GTX 970 has a 173 MHz higher core clock speed and 16 more Render Output Units than the GTX 780. This results in the GTX 970 providing 26.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GTX 970 was released over a year more recently than the GTX 780, and so the GTX 970 is likely to have better driver support, meaning it will be more optimized for running the latest games.
Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.
The GTX 780 has 2048 MB more video memory than the GTX 970, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 780 also has superior memory performance overall.
The GTX 780 has 64 GB/sec greater memory bandwidth than the GTX 970, which means that the memory performance of the GTX 780 is much better than the GTX 970.
The GTX 970 has 1664 Shader Processing Units and the GeForce GTX 780 EVGA SC w/ ACX 6GB Edition has 2304. However, the actual shader performance of the GTX 970 is 2873 and the actual shader performance of the GTX 780 is 2350. The GTX 970 having 523 better shader performance is not particularly notable, as altogether the GTX 780 performs better when taking into account other relevant data.
The GTX 970 148 Watts to run and the GeForce GTX 780 EVGA SC w/ ACX 6GB Edition requires 250 Watts. I recommend a PSU with at least 500 Watts for the GTX 970 and a PSU with at least 600 Watts for theGTX 780. The GTX 780 requires 102 Watts more than the GTX 970 to run. The difference is significant enough that the GTX 780 may have an adverse affect on your yearly electricity bills in comparison to the GTX 970.
