What Driver is everyone on?
I don't remember bad drivers from nvidia, so the latest is usually the best option (and sometimes also the fastest for some miners, sp-mods for example often work better with the latest drivers). I'm running 388.31 on a couple of rigs and don't have any problems with them.
Since 387 i got 15% lower hash on neoscrypt on 1070 but 1080/1080ti is not good on neoscrypt so probably the last one are fine. Dont know if any other algo is affected. 385.41 works fine on neo. Dont know when nvidia broke them.
