''-w 2'' together with ''-n 32 -u 1024'' does not make any sense. Use one or the other. The latter is sub-optimal. Ideally you should use neither, and use -w 3 instead.

Further, Titan Z is not the Titan X. Titan Z will be ~ 20% slower than 2x GTX 780Ti, so roughly 140 KH/s when properly tuned.

Then do the math: 95^8 / 140000 / 31556926 =~ 1,502 years.
