Here you wait up to 3 Month for good GPU.
5 Mh/s = 7 R9 280x
7 R9 280x = 1750 Watt
The Alpha Miner need 100 Watt. (Scam is always possible ...... )
The Rig with 7 GPU can you not realize because I don`t know motherboard with 7 PCi/e slots.
For 6 GPU yes (today arrived
)
I can compare both maybe in 6 Month. Let see whats going on.
