6X rx580 4gb mining rig - mining profitibility

[torpedo1985]

Hi

I've been mining ETC on ethermine now for a couple of months. I done some bios mod and overclocking and got 28Mh and then it went down to 21, so I recently did dagfix and now doing no more than 25Mh.

I have to questions now if you guys can help:
1. Do you think I can get more hashpower now?
2. Is there any other alt that is significantly more profitiable to mine now with this gear?

Thanks a lot guys!
