Nope. You said 1 card costs $2000, and 1 card will use over 500 watts to get the same hash power or it will hash a lot less.
He said, she said... I hate taking sides but just post the quote where dogie said 1 card cost $2k. I looked at the first page of this thread and did not see that.
dogie probably overreacted. What does "suitable" mean anyway? It's all relative to the buyer. It's not a Nvidia vs AMD mining comparison. It's more of a power-draw vs price vs hashrate suitability discussion.
Edit: changed 1k to 2k typo
