To update the nvidia driver is a pain in the as within linux. But I think jk_14 will make a update soon.
If you interested how to do it in kopiemtu, i'll could write a little how to.
cudaminerBBR gives 1760hashs per second on a 980 // -l64x256; compiled with compute.50.
that means nearly double hashrate in comparison to my 750ti.
Thanks for the kind offer of a 'how to' but its ok. I've used Linux for a few years and can run either linux or windows on my rigs, also got no desire to mine BBR with the 970's at the moment.
...which algo? the system draw depends extremly on the used algo.
short test with the EVGA 980 SC ACX 2.0 cards shows that they are not beating the 750ti in hash/watt ratio at the moment.
Now it depends on the optimization of our ccminer-dev guys... hooorayh for you all!
To be honest I cannot recall what algo used 380w, prob M7 or scrypt-jane, it was over a month ago.
Looking forward to optimizations that may come our way over the next few months.
