Hello to everyone!
I am a new member on this forum so I would like your opinion on some things if possible.
I want to begin mining and I have found different opinions on this subject, regarding GPUs, what to mine, profits and so on....
My plan is to mine Eth but I have found that 1080 ti is not the best option for that, Eth is also dropping down on the market, the thing is I want to start making profits ASAP (not in the long run).

Due to those searches I have decided to compare these 2 GPUs:

MSI RX580 ARMOR 8G OC, 8GB GDDR5, 256bit - 550eu
ASUS ROG-STRIX-GTX1080TI-11G-GAMING - 813eu

Both have same warranty, so which would you prefer as a best buy?
(any other suggestion is welcome)

Currently I have I3 2nd generation sandy bridge with 8gbs RAM and 1TB HDD so I wont be building a RIG (lets see how the profits go on this PC with one of the above GPUs)
I don't want to waste money for 1080 ti (if not needed) but also I wouldn't want to stay outdated with the RX580.

Thank you in advance!
