Reply to comment by Star-Bandit in GPU QUESTION by Nerveregenerator

Actually after going back over the data from the numbers perspective regarding the two cards (bandwidth, clock speed etc,) the 1080 Ti certainly might have the upper hand, I'd have to run some benchmarks myself

I think you way overestimated K80 performance when my 4GB GTX 960 back in the day could trade blows with a K40, which was a bit more than half a K80. In a straight memory bandwidth fight, like Transformer model training, the 1080Ti is going to win hands down even if you have perfect scaling acorss both GPUs on the K80 and that's assuming it doesn't get hamstrung by the ancient Kepler architecture in any way at all.
