GTX 670 upgrade?? 1060 or higher

[sickpuppy]

Hi all,

Currently got a 670GTX in my machine, getting about 880 Mh/s on NTLM.
This is basically the only hash I'm cracking.

Is it worth upgrading to a 1060 or would it not make much difference?

Thanks

Thanks for that, did a search but didn't find that thread. 
For the amount of time I spend cracking NTLM I think I can justify a 1060 but not much more.
