Well there are some very good GPUs out there :
This is a RX 580
I own a 570 gpu.
Or a 1080 Ti
Note click on the images
Both are very good for mining but a 1080 Ti is very expensive .
Latest news tells us that soon the prices will drop for 1080 Ti so I will monitor this as I want about 10 GPUs .
I strongly recommend not to buy at 1.4 k a 1080 ti and wait until the price goes down between 200-300 $ even more if it will be possible.
It is very expensive right now at about 700$. Do you think the price will drop down so low to about 200$
I do not know...but I do hope that the price will drop soon as I am very interested to buy one more gpu for my rig.
What is the best coin that can be mined?
