1080 TI - new best bang for buck?

[Flomac]

So at $349, the GTX 1070 is the best bang for the buck.

Yes and no. If you compare single cards, sure. But these cards work in a whole system, so we have to compare system prices instead of single card prices.

E.g.: add $600 for a double slot system and calculate again with 2 GPUs:

GTX 1070:  28.54 MH/$
GTX 1080:  31.25 MH/$
GTX 1080 Ti: 31.0 MH/$

So a standard 1080 is the best and the 1070 suddenly the worst bang for the buck.

For more or less GPUs it goes the same.
