I have some AMD (5850, 6950, 7970) GPUs and want to mine some XMR. Do you think it is still profitable to mine XMR at this point?
If you have free power or believe XMR can go up in value and are willing to hold onto what you mine for awhile.
Doesn't have to be free just cheap. The main obstacle to mining at this point (even with free power for that matter) is the cost of the hardware but if you already have hardware it may be worth it.
