OK so I happen to have enough spare parts to form the basis of a new mining rig - that being an old 2500k CPU, Gigabyte mobo (5*PCIE), RAM and a 5400rpm HDD.
I have been mining for a few days on my GTX 1070 at 29.5MH/s ETH and 291MH/s SIACOIN using claymores dual miner. It seems fairly fun/interesting and I believe what others say about people who get into mining today have a 50/50 chance of making 100% ROI. I like those odds
Besides, it's as good an excuse as any to get a new 1080 ti in my gaming rig and push the 1070 to the mining rig. So I did just that and it's on it's way from the 'states'.
Up next I'm trying to decide on how big to make the mining rig? I already have 5 risers on the way and a 1070 ready for it. I'm looking at adding 4*1060 6GB and a corsair gold 1000W PSU. In Australia that's coming in at $1700 AUD delivered ($1280 USD). All RX4** and RX5** are sold out here. GTX1070 costs $414USD and the 1080ti costs $850USD. (I sourced mine through newegg for approx $760USD delivered)
I can see other peoples logic that buying 1080ti is great resale later. And lets be honest, I'd love to game in SLI, but that would kill 6-8hrs a day of mining time. I think I'm happy with the 1060 6GB price point at $270USD. I know I can source them from the states at sub $200USD, but after shipping costs and warranty issues... there's not much in it. Besides, that wont be the factor that makes or breaks the ROI here.
I guess that's about as much as I'm willing to gamble for now. And even if I hit 60-70% ROI, I'll be happy. It's a fun hobby after all.
Do you think $1500 USD is a sensible budget for someones first mining rig? ($1280 + resale value of the 1070)
