Ok Thankyou for you help. Humour me here as I am a bit of a novice as to the difference in cracking rigs vs mining rigs and I am trying to figure out why they are different.
Mining quark I am achieving around 6000kh/s per card with the 750ti or around 36 mh/s per rig for a fuel burn of 400watts. So including associated infrastructure that's 66 watts per card
A 980 will mine quark at around 11900 kh/s not quite double the speed at TDP 93.6% of 165 Watts which is 154 watts not including infrastructure.
750 ti Cost AUD $180
980 cost AUD $700
3.88 cards x 6000 = 23 mh/s for the price of 12mh/s per 980 $ wise
power wise 2 x 66=132 watt for 12000 kh/s with 750 ti
lets allow the 980 154 watts with infrastructure for 12000kh/s and its still behind hash per watt.
please don't get me wrong I am not trying to argue just understand why the two operations are different
If I have plenty of cards to play with I am speculating that the power cost should be slightly better in favour of the 750 ti and I can make up lost time by simply by multiplying the number of cards available. I am trying to make sure that I understand the exact differences in required hardware between each rig and how it impacts its role as either a miner or cracker. I want to build a rig that's running 980 cards just for the sheer power of it so I can mine harder when profits are up and utilize it as a cracker at other times, I thought that the 980 is a little thirsty but better miners are closing the gap.
And as you say I already have the 750 ti
