Here is a quick post listing out all my graphics cards/GPUs and what hashrates I've been getting. This is a constant work so these rates may change up/down daily as I find ways to tweak them.
Mining Ethereum using Genoils console software, connecting to ethermine.org pool:
2 x GTX 1070 8GB - combined average of 59.5 MH/s (overclocked +450 Mhz on memory clock only)
2 x GTX 970 4GB - combined average of about 7MH/s (just got these and trying to tweak them, many have this same issue)
1 x GTX 960 4GB - average 11 MH/s (overcocked +50Mhz on proc and +500Mhz on memory)
1 x AMD Radeon R9 390x 8GB - 28.5 MH/s (base GPU overclocked memory to 1560Mhz (+60))
My combined hashrate jumps as high as just over 110MH/s, but my averge is around 100MH/s
Mining with lower end GPU for Monero using Minergate GUI or Console:
2 x GTX 960 2GB - combined 280 kH/s (base no overclock)
1 x GTX 960m 2GB - 58 kH/s
1 x GTX 730 4GB - 3.3 kH/s (will not mine ethereum even with 4GB memory)
I also run all of my processors across 5 desktops, 1 laptop, and 6-10 android devices between 60-85% processor utilization for Minergate GUI or console for Monero.
Hope this gives you guys some ideas on output ideas for your systems and encourages you to get to mining.
