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.
I suggest you go to this site and work out the hash rate/second of your systems.
https://en.bitcoin.it/wiki/Non-specialized_hardware_comparisonFor the purposes of this discussion we will give it a fast graphics board, say 500 megahash/second, or 0.5 gigahash/second. This would earn about 2 cents a month as a Bitcoin miner.
A single typical ASIC miner runs at about 5,000 Gigahash/second. This is 10,000 times faster than your PC.
So if you have 10,000 PCs you may have the same hash rate as 1 ASIC miner (S7) and earn about $200 this month, and less in following months. You will also generate an enormous electricity bill with the PCs.
The total current hash network runs at 1,100,000,000 gigahash/second. This is about 2 billion times faster than a high end PC.
So even if you have a million PCs it is still hardly anything. The days of PC and GPU Bitcoin mining have long gone.
The only possibility for you is mining some alt coin. Also if you don't own the PCs, and pay the electrical bill yourself, you may end up in serious trouble if you do not have the owners permission to use the PCs this way.
