RE: Gridcoin Mining with 80kW of hydroelectric power (Phase 2)
if you thinking about FP64 maybe you should check out used 7870 they have 0,7 tflops in fp64 and 3tflops in fp32, you can get them for around 100$ or if you want also better performance in fp32 you can check R9 290X they have 5,6tflops in fp32 and 0,7tflops in fp64 for about 150-200$.
They are cheaper to buy, but are used and without warranty. The overall efficiency (FP64/kWh) is equal or less than on current RX Vega 56, and much less on FP32, so that's not an real option.
