Thank you everyone thus far for the replies, I certainly appreciate them. I'm hoping to start building sooner than later but it seems I may have MOBO, PSU, CPU, and ram before I get any cards (not for lack of funds, but supply). Then again it seems a lot are in this boat.
You might be able to build a 6x AMD Rx 580 4GB rig for $2000 or a 6x Nvidia GTX 1070 rig for $3000. This would be based on USA sale prices... most other countries in the world will be more expensive. Based solely on the prices of altcoins today I would find the Rx 580 to be a quicker ROI, but the GTX 1070 is more versatile (which bodes well for the future). AMD also requires more fiddling with to get optimal performance, which may be a negative if you are new to mining... on the other hand a $2k rig is allot cheaper then a $3k rig to start out with.
I'm finding it more and more difficult to piece a build with all of the shortages and price gauging. I had found the h110 BTC+ at MSRP this morning and failed to pull the trigger fast enough and watched it turn from in stock to OOS in my cart!
I've seen a lot of builds with 1060's; I think they are great. In regards to sustainability I'm wondering if 1080 Ti's are going to be the best route.
I guess my choices are...
(2) - 1080 Ti's
(4-6) 1060's; 1070's; or 1070 ti's
Anyone able to weigh in on wether these would be reasonable options in regards to sustainability aka future mining opportunities?
It is better to think of no resale value. The cards break under intensive use.
I hear you there and I am definitely aware of the risks of no return.
