If you mine for zcash i would greatly appreciate any info on what gpu you are using and how much hashrate they are giving you. So that i will have a good idea on what hardware i should invest in, thank you guys very much!
Count in the fact that some GPUs use more power than others. I'm undervolted and the cards below could easily do about 30-40H/s more if electricity is no concern for you. I'm at 0.23cts/kw so I'd rather hash a bit slower and use less juice.
RX470 4GB : 200H/s (can do 220+)
RX470 8GB : 225H/s (can do 260+)
390X : 320H/s (can do 350+)
