My rig certainly isn’t fast by any means. But I have a XFX 6670 with 1gb of ddr5. I get around 105-110 kh/s it’s also paired with my a6-3670k apu that gets about 50 kh/s.
Edit: the apu gets about 50 actually. it’s got a nice overclock on it. Also the Gpu stays near 52 C and the processor stays near 30 C
