I tried with ethos and The-Distribution-Which-Does-Not-Handle-OpenCL-Well (The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali)) with i73840qm but with -m15700 benchmark mode i see opencl errors... its linux drivers fault and should i try with windows? or this cpu is too low ?

Ubuntu 16.04 and Windows 10

I'm not sure what the current performance of -m 15700 is with a 1080 ti, but you could just test it or look for benchmarks.

Anyways, scrypt is known to be GPU-unfriendly and therefore a modern OpenCL-compatible CPU will be a good idea to crack a 15700 hash (what might be even better is to have a good strategy on how to attack the hash: a plan to generate/use the most likely password candidates... a "small" set of candidates of course, because scrypt is slow... but this is of course a different topic).

Not what i wanted to hear :'(, and all my RX570's are useless too! 

Don't mean to take over the thread but Phil, we've been in contact via email - You mentioned hashcat and ive spent the last gods knows how many hours taking in information. TLDR; my case scenario it may not be achievable.
