Going to choose from few old GPUs from a friend of a friend that needed money and want to sell them, what will be the better decision between 1080ti and Vega 64? Which one is more durable for mining and give less stress or troubles?
I believe you are asking a rhetoric question here,it is surely 1080 ti and although it doesn't go to 50 Mhsh like Vega does,max it goes 46-47 Mhsh at full power of 220 watt while Vega stays 190 watt at 50 Mhsh the problem is Vegas need much more care while the 1080 ti card is a set and forget one and I am talking from experience,I got a few dead Vegas while my only one Gtx 1080 ti Evga FTW3 is still running strong and extremely stable with temperatures staying at less than 50 degree celsius most of the time something you cannot find in a Vega.
I would surely sacrifice a few Mhsh to have peace of mind and much longer lifespan with the Nvidias.
