hey guys !

Im new to mining and like so many others I tried minegate first. Auto-mining chose XMRfor me.
My system is a xeon E3 123 v3, 8 GB DDR3 Memory and a AMD Radeon R9 390. Not top notch, I know...

So far with minegate I get around 120-140 H/S with CPU mining and around 40-60 H/S with GPU mining. But Im reading about mega hash rates here. I dont even get over 3,6 k Hash/minute with my GPU. Is that because of my slow hardware, the bad mining software or maybe because of some other issues? Im no way near 1Mh/m atm...
