I have a question for you all 1080ti miners. I plan on buying couple gpu (i prefer Nvidia), but it seems to me that rx Vega is much more profitable and even cheaper than 1080ti. What is your opinion?
I own both on a few rigs and I wont ever purchase another AMD GPU in my life even if there was a nice discount

Why not? At first I also thought that, but lately my Nvidia rigs are crashing while AMD rx 470 and 480 are working perfectly without any problem... When you consider price of gpu, power consumption and hashrate, seems like vega is almost 2 times better choice than 1080ti...
