This is an honest question. Why would you throw money away buying a bleeding edge graphics card when you can buy 3-4 other cards for the same price with a combined hash rate that will shit all over that card for overall value and hashrate?
edit: You can buy 5 RX470s for the same price as the one Ti.
Hmm...
5 x 470 = ~140 Mh/s on ETH which is about $16 / day
1 x 1080ti = ~1000 Mh/s on Skein which is about $16 / day
I'm not even going to talk about power consumption or space savings in this scenario
