Mining with CPU hasn't been viable for over five years and GPU hasn't been viable for going on three years.
ASIC mining hardware is now required to mine Bitcoin.
all good, i have many servers with very high specs, i am not talking for a 1 machine job. i have a bunch of servers.
High end servers aren't going to have good AMD gaming GPU's, they typically have Intel GPU's which never were any good for Bitcoin mining. Even if they did that still wouldn't equate to one current Bitcoin Miner. So get an Avalon 6 or a Bitmain S7 and put in your data center.
