To get to earn let's say 5 $ a day how many gpus do i need? between 580 and 1060 which is better for mining?
4-5 1060 6GB will net you about $5 per day. 5 if you are paying electric at normal costs per kwH. The 580 is about 5MH/s faster than the 1060 6GB (both at standard clocks) so that would be a better bet than the 1060. I have one 1060 and one RX580 8GB.
