First of help,thanks for all the discussion on the boards it is very insightful and helpful. I have been lurking around for a while and I am getting the itch to build a rig. I have been trading bitcoin and various alts for little while now and am not sure if I have what it takes to keep trading, nor do i want to tie up money in alts as longs. I have been doing exceptionally well however with the way crypto swings this could change instantly. My thoughts on a gpu rig is that I would still be in the game with the gpus as a hedge, no its not the same get rich quick but if you own the hardware it is irrelevant what the coin price does (to a point).
On to the rig, I have selected two different gpu systems.Both 6 card.I initially want to mine but not limited to monero.(also interested in eth and others of course) I am leaning towards rx580 as they are $310 usd each compared to 1070ti at $525 usd as well better at cryptonight. Vega 56 and 64 are unavailable for the near future and start at $600 usd each if they were in stock. There is also the possibility of waiting for volta but who knows if it will be worth the wait.
With cost and longevity/return in mind what would you go with.
